Can someone please help me price my PS2 collection? (Reply soon please!)

EDIT: Problem Resolved! No-one replied so I took the long way around and did it myself. (a.k.a. finding the used price for every game individually and then adding it all together.)

So I called Elite Gaming in Fontana, CA today and I asked the guy "Do you buy PS2 games and consoles?" He told me that he wanted to know how much I was asking for everything. He also said that he doesn't buy them very much unless he can get a good deal off them and get rid of them. SO, I need some help pricing, it would be really helpful since I don't exactly wanna over-do it or under-do it (Trying to upgrade to a PS3 with the money) Here's my list of stuff

PS2 Slim (working) with 2 memory cards, 1 controller with a somewhat messed up rumbler thingy. The PS2 also has to have something on top of it's disk tray or it usually won't read discs. Sometimes the game will freeze or music will replay or shuffle around during the gameplay but those problems can both be easily fixed by moving around what's on top of the disk tray, the game will resume. Estimated Price = $25-$30

I dont have any experience working at a gaming store, though I have traded in a reasonable amount of games in the past. I would say you might be able to get like $125 for them all, though that may be on the high end...
