It retails for over a thousand an looks like new.....and you are saying 450 is too much.......I dont want to give it away......Play it Again Sports offered me 350 for it.
Alaskan Thunder was right about Whirlwinds being sold at a much lower price... But if Play-It-Again-Sports (Asheville?) is offering $350 for it, then:
1. It's basically in mint condition (can't really see from your pictures)
2. They prolly have a buyer willing to pay $500-$550 to them, as a local dealer.
If you have the time, then keep putting up your table on Craigslist and maybe you'll find that buyer. But keep in mind that buyer wouldn't really consider paying you close to what she or he'd pay a reputable dealer like P-I-A-S. Might be a corollary good customer of theirs already, who's been buying or bought other stuff from them.
