Ever sold concert tickets on Stub Hub?

I have too many concert tickets for a couple shows coming up that we decided not to attend since we just had to get a new roof, so I'm looking to sell them.  I know you can sell tickets on Stub Hub.  If you've ever done that, can you tell me your experience?  These are very good seats, and all I really want is face value, but of course Stub Hub charges a small fee, so I would have to price them to cover that.

Anything you can share about selling through them (or ebay, which owns Stub Hub, so I may as well just go with SH, huh?) will be appreciated.

Thanks!
