I have seen asking prices all over the place. Two that I almost bought was one went for $350 on ebay (no reserve auction) and an hour drive from me and the other was only $500 on Craigslist for an entire nice pump stand but was about a 6 hour drive. I have an eye on one that is $450 and about an hour and a half drive. Most ask $800-$1,500 but I have seen many way outside of those prices. If you don't want to sit on them ask $800 each. You might be able to get a good bit more if you can wait until someone needs one bad and does not want to pay $4K+ for a new one.
