I have two, a Beseler CB7 which is the main enlarger I use for my 4x5 work. I have lots of lens and boards to go with it so I use it for other formats as well. I also have a Beseler 67C, which is the enlarger I bought 30 years ago and is mostly in storage these days. I was just given one of those portable Russian enlargers in a suitcase. I wont use it other than maybe to do a couple of prints to see what you can get out of it.
I have two.
Omega DII (without the crank but with a variable condenser) is my main one
Omega D2 (with the crank but with fixed condenser units) is a spare
One Omega D-2V, one Omega D-2V using a 3-condenser set or an Aristo cold light head, one Omega DM point source enlarger with two heads and 4 condensers, and one Focomat 1c for 35mm. I also have a stored Omega B-8 that belongs to my daughter.
I usually use the Omega D-2V. Darkroom is 10 years old and is 9' X 8' with a Leedal 20" X 60" stainless sink ordered by Kodak, but not delivered.
2 active 4x5 enlargers and 2 further enlargers in storage.
2 Zone VI type 2 VC
1 Beselser 45V XL
2 Phillips Tri-Color 150 Would like to find a home for the 2 Phillips
Down to one, sent a D2V to the dump during a citywide trash pickup 3 or 4 years ago.
