I've got two, but only enough space to use one at a time. The one in use is a Beseler 45MX with an Aristo cold light head. I've also got a Beseler/Minolta 45A head for it, which I'd like to try using, but it needs parts which the budget doesn't currently support. The one in storage is a Beseler 23CII with condenser head. The best part of that one was the price - free! It's in cherry condition too; apparently my uncle used it very little, which is why he gave it to me.
