How much does the first verison of the psp cost now and days?

I have the first verison of the psp and I have a few games and I was wondering how much the old psp would cost because I'm thinking about selling it. It's barely used btw.|||They are selling for $119.99 at gamestop, so expect around $90.00|||It just depends on where you live, like in the mid-west there selling for around 50 dollars but if you really want to sell it, Ebay is the way to go. the games will go for around maybe 10-20 each depending what they are again.|||about 200 or 300 !!!!!|||SOMEWHERE BETWWEN $150 DOLLARS OR 160 DOLLARS|||obout 70.00
