Got a set of 57/08's on TGP and it was great. The guys there are serious about buying and selling, vs eBay which has become a fantasy land for people because they can back out of a deal with no consequences. eBay if you can't sell anywhere else. Don't be tempted by ebay's shipping discount, you can't insure your big ticket items through them (at least that I know of), and if something happens during shipping, eBay holds the seller responsible. Also heard that UPS often won't pay an insurance claim if they didn't pack the item themselves (UPS store, etc). Fedex may be similar, not sure. You definitely want to take the proper steps to cover your @$$ if you're selling on eBay and/or shipping guitars or amps. Went through all these questions myself a few months ago, sold my item, but it was a pain, and between shipping and ebay fees... ouch.
