The guy that sold me my Speed Graphic also wants to unload his Beseler 45, with lens, for $120. The idea that I can have an enlarger that'll do all my formats has me drooling. There's a catch, though. I've really gotten used to the Dual Dicro color head on my 23c. Can I take that off and put it on the 45? I just don't have enough room for two enlargers, so if I could swap heads, I could get rid of the 23c.
