Hey guys. I want to be among the "hacked" PSP community and I have some money lying around and an unwanted DS. So I thought I might as well go to Gamestop and trade it in for a PSP. However, I am curious on to what starting firmware I am willing to expect to get if I do buy a new PSP. I did some researching and so far it seems every firmware is hackable (Medal of Honor 5.51 just hasn't had anything done with it yet). I want to avoid waiting if possible. So Is there any PSP's I should avoid buying if I want to hack my psp? Thanks for the help.

Also, it seems as though I may only have 3000 models to chose from.
