I have a Fujimoto G70 colour enlarger which caters for 35mm to 6x7 and has a built in timer and a very high column for big enlargements.

The best thing about this enlarger is the reversible light source which can switch between condensor and diffuser. Best of both worlds

The following site has one of the later version (VR70) for sale:
