I'm just digging through this finally. Honestly, I have shied away from the Kayfuns due to how many different models and versions there are... a bit overwhelming. I've decided, I'm going to build your rig and give it a shot. It sounds like it works very well. I started poking at the links and around FT... holy rat butts, Batman, there are a TON of parts for these things! How can you know what parts fit with what other parts?
Anyway, I'm going to get the base you recommended, but, of course, in black. I'll probably get the same translucent tanks. Looks like I have to get the barrel/chimney set as the other barrel onlys are out of stock. Have you seen any black barrels anywhere?
