If you are not opposed to dealing with E-bay, the "vintage" bows can do OK on there.
Parts are usually hard to find in good condition, a bow that is complete and in good shape will probably move if you price it right.
IMHO - about $40-50 to start is probably a good idea.
I actually picked up a Martin Warthog Magnum over the weekend at local gun show - just because - beautiful wood riser, rosewood tips, barely used, and vintage accessories - 190 FPSish with aluminum telephone poles...
