I should add that the D2 (or DII) is somewhat large but not bad for a 4x5 enlarger. A bit larger and significantly heavier than the Beseler 23; a bit smaller (but not much lighter) than the Beseler 45.
Make sure you get as many negative carriers as you can. Also, both the D2 and the DII will use what's called a "lens cone". There were 2-3 different sizes for different focal length lenses. It would be a shame for them to get tossed into the trash if separated from the enlarger.
