The words cheap and Leica Focomat 35 tend to be mutually exclusive. It is probably one of the most expensive 35mm enlargers. Some would say its the Rolls Royce of 35mm enlargers
The Durst range might meet your specifications. In my experience the M605 might meet your requirements. It is a fairly robust enlarger, covers up to 6x6 negs and comes with a dichroic head for colour work which might be useful.
It might help us of you specify your price range and to our N American contributors can I say that Beselers are fairly rare here in the U.K. and the OP is U.K. based.
