i don't have much to contribute, other than stay the hell away from the shitty graham condensers. they are not worth it. they clog with condensate and require constant dilligence. if you choose to disagree, you can buy SWIMs for CHEAP!!!! (kidding, no commerce on the HIVE)
SWIM has a six bulb, 300mm allihn that has served SWIM well. it was cheap, and has been very sturdy and useful.
i learned a thing or two from charlie dontcha know.
