So all I would need is: the controller, the v-rod flower pot head and diffuser (says it includes the sic dish) and the carb cap?
You'll also need a bowl - the Ti ones are more expensive than the glass ones, but they're also unbreakable. And with the double weave screens, they do an amazing job of keeping particulate matter out of your piece. I do like the taste and simplicity of the glass bowls, though.
The enail handle isn't a must, but nice to have... same with one of their stands (the $30 one is what I use) but you can use a ceramic mug in a pinch so, kinda at your discretion.
As long as you got a coil in there too (20mm) you should be good... I could be forgetting something, but I don't think so...

Sounds like if you get a vrod, you may be on a direct flight to Rosin-Land. Buying a press is at the top of my list for sure...
