I've read the stickies and it looks like the early versions of the PSP 2000 is the best way to go for custom firmware and the joys it brings. But I read in another site that the PSP version doesnt matter as much anymore since even the PSP Go can run custom firmware now. I havent been into the PSP scene since I have been way too busy with my DS but I figured I should branch out and maybe even get nostalgic with the ps1. I am able to purchase a PSP 1000 , 2000, 3000, and a Go. Which one should I get for the ps1 games and psp games? And are there certain things I have to watch out for like permanently screwing up the unit?
