Currently two Beseler 45s. One early (tapered bellows, front supports), one late (square bellows, rear supports). Both have 45s heads, one with a 6x7 mixing chamber, and the other set for 4x5. I also have a condenser head and an early cold light for them, but rarely pull them out.
I have a Durst F30 and M605 tucked away - the F30 column makes a good copy stand.
I had an old Russian 'suitcase' enlarger once, and an MPP 6x6.
An Omega DII that I bought shortly after my second job out of school. I am still exploring the mysteries of cold light with an old Aristo grid. I know how I keep exposure consistent but I wonder how anybody else did.
I have two enlargers set up in my darkroom. IFF Ampliator colour enlarger for 6x6 - 5x7" negatives and a Dunco Modell-II 66 multigrade/colour enlarger for 35mm and 6x6. The IFF is a large floor standing enlarger, so heavy that I hope I'll never have to move it again... The Dunco is also very nice, and I think you can still get it new (as Modell-II 67).
