The film size you use will be part of the equation.
If you decide on Durst, my choice would be the 670 or 800 models because I've got both 6X7 and 6X9 cameras as well as 35mm.
Different types, you know are VC, color and condenser, so.....
*Condenser type is likely to be the least expensive and most common. Thousands of people started with, and continue to use them.
most later(!) models have filter drawers for variable contrast filters
*Color heads are diffusion type will use dichroic filters to change filter. The filters can be used with color paper or variable contrast.
*VC types use variable filters like a color head, but only have two colors rather than three in a color head.
There are dozens if not hundreds of books on darkroom techniques and I'd start with a bit of reading.
The person who aided in your darkroom experience can give you some important first hand advice.
