Tough call. Lots of people can't even give enlargers away. The lenses can be worth a little bit, but trying to get much value out of the kit is going to be tough. Too many people have gone to a digital darkroom, even the film shooters. My gut reaction says that someone might be willing to pay $750ish to get a nice fully functional darkroom, but I'm guessing that's a lot less than you were expecting.
I'd try posting it for sale at APUG or Large Format Photography Forum, since that's where most of the traditional guys hang out. I've seen some kits there posted in the $1k to $1500 range, but unfortunately they didn't sell. Try for a local sale there, and don't forget to post it to Craigslist to see if you can get a starving artist or college student to buy. Unfortunately shipping would be a deal killer.
If you can't sell the kit, then sell just the lenses on ebay, and donate the rest to a school with a photography dept for a tax write off.
