Going on the older end of the scale, cruising craigslist and the local dealers. Trying to keep it around $5000, but everytime I find a decent rig, it is gone before I can get out there. Just venting...
Eagle Cap would be another one to add to your list. I found mine by cruising Craigslist in areas that were low population. Spent 2 months looking and checking out possibilities before finding mine. They were asking $14k and drove it home for $9k. Cash works.
