Challenge: $500 or less...it is Projekt Uber Geizig! Total budget planned to be less than $1000 for a running bus

Even more of a challenge...I am looking for a bus with a straight body, good title, motor running hopefully or something I can rebuild. Don't care if it's a bus or camper but I would prefer a Westfalia w/ camping accessories (cabinets, sink, fridge) - it would be cool to have a Westy.
Anyway, whatever you guys find, please let me know. Pics are a huge plus.
FTR, I found one in Helena on CL: http://montana.craigslist.org/bar/1647236706.html BUT no reply. Anyone up there know who this is? It would be a perfect project.
