Yes the D2 and D2V require accessories like different length lens cones for a different lens, and different neg carriers and in the case of the D2 different condensers for different formats. But it is a long time durable workhorse that is still being used by a lot of printers. It can also be easily adapted to a coldlite or you frequently find them for sale set up that way.

There are newer and slicker units out there but that usually means more $. The omegas are plentiful, cheap, adaptable and rugged great performing enlargers. They are good enough that Harry at this site:

seems to make a good business out of selling reconditioned units and parts.
