I just bought a Used PS3 with backwards compatibility, upgraded 500 GB HD, in original box, PS3 remote, 2 games, 2 controllers, 2 charger cables... Was $235 shipped!
If Ginger decides to listen to this guys dumb suggestion, he will never sell it.
That 160 PS3 is going for $140-$180 used online.... One guy is selling a 160 with 37 games!! and it's only $250!!

I would say around $200 max with free shipping is what you can get with the whole bundle. I would do a buy now of $200 and start at $125. Someone may bite on the buy now price, otherwise you'll probably get around $180, the problem is the accessories usually won't fetch a ton if bundled, you may want to sell everything separately.
However looking again at your extras you may not, the camera is nearly worth nothing now, same with the keyboard, extra controller is nice. Only real thing of value is GTA, but even then maybe $25 used, and Bioshock is worth nearly nothing.... so yea I would consider you lucky to get $200 total.
