Wow, that was a lot to read! To avoid going through it and making a huge post in response, I’ll just try to cover the main things I think you want to know.
1. Dynavap.com is a good place to buy the Omnivap XL...someone else might know a place that sells them a little cheaper or has a discount code, or you could wait for a sale from Dynavap.
Right now they’re doing limited runs if anodized titanium in different colors if you’re interested.
I’d also buy extra screens (they last but could get lost), and maybe some degummed hemp fiber if you think you might want a filter to keep any larger particles out of your mouth. Dynavap sells that too.
Oh, and a magnet would be useful for removing the cap and/or holding it on your desk if you don’t buy a Dynastash which has a magnet in it.
2. For the FlowerPot, the minimum you need is an enail controller, a 20mm coil, a head, a bowl and some extra screens. Oh, and a bong/bubbler/j hook/etc. to put the bowl in.
NewVape sells a decent controller and coil (and they just started selling a battery and cage for it for people who want portability).
They have some decent Chinese glass too. I like the stereo matrix I got from them, but it’s a little cheaper direct from China if you can wait.
For bowls, some people have preferences for older models, but they could stick in your glass so I think most people prefer the newer PanHead and ShovelHead bowls that are adjustable to your piece and don’t stick. The only differences between those bowls are looks and a little more or less metal.
The main choice to make is the head. Here’s who I would recommend each one for:
The ShowerHead for anyone only interested in flower and not concentrates, or who wants great flower performance and is happy with dabbing off of titanium.
The VRod for anyone who is into concentrates and is willing to use NewVape’s controller and coil or who wants to find another compatible coil or do some soldering to use it with another controller.
The Wrap-Around (or D-Nail compatible Wrap-Around) for concentrate users who want to use a different brand of controller/coil and are willing to sacrifice a bit of performance on flower.
The VRod and Wrap-Around do also need a dish for concentrates, and they cost another $10-60+ depending on what you want.
You do also need somewhere to put the hot head while it’s not in use, but that could be as simple as a coffee cup or an ash tray or something. Some people also just buy the threaded post they sell for it and put it I to a piece of wood rather than buying the stand.
From there you can get whatever else you want and can afford. The stands are nice, the carb cap is a good idea if you use concentrates but optional for flower (it does provide a bit of draw restriction if you like that), double weave screens that are more durable, a handle if you want one and don’t want to make it, etc.
The things I listed first are all you really have to have though, and since titanium is very tough and enail controllers are pretty reliable it should easily last you 5+ years.
I wouldn’t try to steer you away from the E-Nano or some other great vaporizers either, but you did say that sometimes you want to use a lot at once...
With the E-Nano you have the choice of a small load, or a smaller load. With the FlowerPot you can use anywhere from crumbs up to like .3g at once I think. Plus you can use concentrates through it, even at the same time if you want to.
I hear the E-Nano is still pretty hard hitting for a lot of people, and if you don’t mind reloading more you may be totally happy with it, but if you know you want larger amounts in a single hit sometimes the FlowerPot is the better option there. You may find that you need less flower than you expect with either though!
I’ve never tried The Herbirizer either, but the design does have a lot of similarities to the FlowerPot and plenty of people like it so I’m sure it’s also a good option.
I think it’s cheaper than the FlowerPot, at least in Europe, and I don’t think it has the same concentrate options available, but if it looks good to you and you can get a better deal on it, I think it’d also be a good option. The Evo and some others too. You already know which one I went with though.
Lastly, on the Volcano, it still gets a lot of praise and I’m sure it’s a great option for the right people. I was about to buy one myself when I learned about the FlowerPot, but what really changed my mind was thinking about how the Volcano is used.
You load a good amount of flower into the chamber on top, you put a mouthpiece with a large bag attached to it on the chamber, you turn on the fan and it blows up the bag with vapor, then you breathe the vapor out of the bag. You should use it all pretty quickly after filling or it can start condensing on the bag a lot and start tasting stale from what I’ve heard.
Some people like this style and it’s got some possible advantages, but to me the FlowerPot is just a lot more simple to use and I can use exactly the amount I want at any time.
Since you asked about noise, the Volcano is also the only one of these that really makes noise (due to the fan that fills the bags). You may make a little noise with the others if you run them through water, but you can also use them dry and there won’t be any significant sound unless you make yourself cough.
I hope that answered most of your questions!
