The only one that I know of that is worth while in your price range around here is a 1995 E320 wagon. Pretty nice shape other than a few dings and scratches. The interior could use a detail too. It runs a drives nicely, the only problem I'm aware of is the dreaded AC evaporator, so no air conditioning. Wiring harness looks to be replaced though.
Its an awesome trip if you head up through the mountains. Vegas, Utah desert, all the ski resort towns on I70. I just did it recently and documented it here.

Here are some photos of the wagon. Its owned by a good friend of mine here in Wichita. I believe he wants 3 grand for it.
