Like she said! Nothing personal, but folks should at some point learn to go back and read a little of the thread they're posting in. Know it can be a bitch - especially as fast as this one moves - but it's really not that difficult. And, try to consider how much more this thread gets bogged down with so many people coming and asking the same things.
As far as what they're usually asking.... IMO it's a good idea to look at all out there and take the plunge at what you think looks best. What I like (or what 10 FC'ers may like) may not appeal to anyone in particular. A couple of examples... for a few reasons, I love me a sidecar. Not everybody will like one. I also try to have minimal diffusion to keep the most flavor. So, stacking bubbles all the way up the can doesn't really appeal to me. Sure, it's cool to see and fun to do, but not something I want to be doing all the time. I'd rather have more flavor.
No way to know if your preferences are the same or totally different unless you start actually trying things out. At about $30 a pop, and a little patience for shipping, you could have a good idea of what you like and want for less than $100 - and probably sell off what you don't like for damn near what you paid for it!
Man up - grow up - whatever, and take the plunge! If you can get glass for about the same price as an 1/8th, and if you don't like it turn around and sell it for what you paid (or damn close) - just do it!
@ataxian ... took a quick pic of D020, D020-W and the jhanpixel sidecar next to it. D020-W is really nice, and probably 3rd choice in my lineup now - but the jhanpixel can be had for $150 from US blower with thick glass and free shipping. Yes... that's 5x as much $, but honestly think I like it 6x as much! Tied for first place here with the nano (my Ben Wilson triple donut also tied in first). You can certainly see which one is most in need of cleaning!
