I did eBay Instant Sale. I know I left about $25-$40 on the table, but it's worth it for the lack of hassle. I got $136 for mine, with free shipping. No hassle, no listing fees. With shipping and fees, a $170 sale would only net about $20 more, with the risk of scam artists and such. Normally don't take the cheaper way out, but with a bazillion 3GSs on sale, I noticed that most were selling now in the $150 or less range.
