This question has been asked a few times over the months I've been here. Try a search.
Personally I got an Omega D2V at home in my "temporary darkroom" (read bathroom). It takes up to a 4x5 neg, but I am currently using it for 35 and 120 formats. Easy to use, not too bad for finding parts/service (in my area anyway).
When you do look for a lens for the enlarger (no matter the brand) get the best lens you can afford (don't cheap out!)
