Since I've played basically every good DS game there is over and over again, I'm considering buying a PSP. Before I do so, I want to confirm some things: I've heard that all PSPs are fully CFW-able and hackable. Is this true? Are all models of PSP able to be CFW'd, regardless of current firmware version? Which model(s) of PSP are the best? Why / what makes these models better? I heard that, for those who are just going to pirate everything, the PSPgo is good. Is this true? Do the different controls make it harder to play games? Thanks!
