The guitarist in my band bought an Ibanez that he'd been looking out for after I passed the link to the auction on and I bought a six-string fretless bass (for just under the lower estimate). Postage isn't cheap (about £50 IIRC) and I went down to pick up the bass, and collected his guitar while I was at it. Buyer's premium was around 25%. With a seller's premium of about the same, the buyer pays around double what the seller receives, which puts Ebay's buyer fee in perspective.
There were quite a few 12-strings, which makes a change. I am a bit tempted by the idea of a 12-string solid-body but managed to resist.
