Ok I'll admit it...

YutrzenikaYou said your buying used? As in, from a Pawn Shop, or from a game store?

Ebay, Classifieds, Craigslist, Pawnshop, etc... Just where ever.

Well here's a page with prices on PS3's, new and used at EB/Gamestop.
I also looked on eBay, I've seen some used for as low as $100, and up to about $350.

Ya, I don't think I'll be going with ebgames or gamestop, it's to expencive.I'll probably end up buying one off ebay, with games included or something.

Yeah, eBay is probably your best bet for getting it.

Does your PSP have a temp firmware or is it a full firmware? (temp firmware is 5.03 GEN-C or MHU usually and full would be 5.00 M33 or 5.50 GEN)I think the PSP could sell for $120-$150 on eBay either way.

I think it has 5.50 Gen D-3 currently, but I'm not sure and I can update/downgrade if needed.So you think I should sell it on ebay?
