NO. The I need to buy a PSP to replace my PSP 1000 I bought off a friend for $40 as it is beat to crap and not working well. The 3000 has some major flaws. It has a shorter battery life and very visible scan lines on the screen. So, either wait for this year's PSP update (the rumored 4000 that will fix the screen issues) or just get the 2000.
Get the 2000. You can use custom firmware on the 2000 model, thus allowing you to create backups of your classic PS One collection and play them on the go. I bought a 2000 just so that I could use it as a portable SNES, Sega Genesis, PSX, and of course...a PSP. Then again...for $77 on eBay who wouldn't do it?
