I have one of those, they are really cool. You can get a ton of awesome fuzzy bass noises out of them, but its hard to remember the settings so I have to make drawings.
I'm pretty set on buying one. I'll probably have to do some maintenance with it. Apparently the caps need to be replaced. I'm worried about it needing servicing and have to pay $$$ to get it foxed
These are also famous for the protective black foam inside turning to a goopy mess over the years, making it incredibly difficult to service and maintain. Chances are, the current owner is not the original owner but can provide some history for you.
I just missed buying a recently-serviced local one, but it's probably for the best.
