I use a Focomat V35 for 35mm, a Durst something for 6x6 and a wall mounted DeVere 5108 for everything else. It takes a lot of space but I have the luxury of a two room darkroom. The Durst is hardly ever used so I could put it into storage with the rest of the enlarger collection (sometimes I suspect enlargers breed among themselves every time I look there are more of them).
