Personally, These days I'm a big fan of Omega enlargers. They are still in production, and easy to obtain parts.I used to own an M-601 back in the early 70's added a dichro head when they became available. Now I have six Omega machines. Four C-700's. a B66 pro lab w/both condenser and dichro heads, and a Pro Lab 4x5. I like having dedicated format machines, and love to collect toys. From a logistics point, this is only logical, as most interchange parts, and I know what each will do without too much messing around.
