Dude buy it as soon as possible coz Sony is going to launch PSP-3000 which can't be modded and will cost about 13K with no hardware improvement except mic and brighter screen which are both quite useless.
Get PSP-2000 for 8.5 K and you get get it modded for 200bux.Get a screen guard for 250-300 bux,a good PSP cover,a 4GB memory stick,you can store 4 games or more depending on their size.Get a PSP kit too if you can for 500 bux in which you get a component cable to connect PSP to TV,a PSP cover(Though I recommend to get a seperate one coz the one in the kit is crapy),USB charger and cable to transfer games and other files from your computer to PSP,screen guard and a UMD carry bag.
