I'll second the Durst F60. I had never personally used a Durst but knew they were good. When I decided to buy a beater enlarger for flashing I found a Durst F60 for $15. Going through it to clean it up I was immediately impressed with its rigidity, simplicity and how the carrier works. It is a very basic unit but I can honestly say if I had to do it all over again and needed a 35mm enlarger I'd probably try to find a small Durst.
