Thinking about selling my PS3 & games have a question

I'm thinking about selling my PS3 and games but I'm not sure where I should start at with the price.

I have a 20 gig PS3 and 37 PS3 games and 4 PS2 games. The only sports games I have are NBA 2k11, MAden 12, and WWE 12. I'm at work so I can't make a list. I have a few collectors editions GT5, Killzone 3, Fallout New Vegas, and Mortal Kombat, 3 controllers one dualshock and two sixaxis and a rockband bundle. I was thinking about asking between $500-$600 for everything.

Is this reasonable?

Its right around a good price considering you only have a 20 GB hard drive. Its a good amount of games but if they are older they may only be worth around 10-15 bucks a piece. The thing that bumps up the value is the backwards compatibility. Shoot me a list of your collection and If you're interested I'll see if I can buy some of em off you.

I would take out some of the controllers and the more popular games out of the bundle and sell them separately, especially the special editions, because you'll net more money that way.

Sell the system with 1 or 2 controllers, and all the sports/crappy games. Sell all the good games separately.
