I suggest that you should buy directly from the store because it's brand new and you can be assured that it has no defects rather than buying from outsiders. The psp is so cool it can do almost everything! I have a psp slim and I'm absolutely loving it!
oh and if you want your psp to have a universal remote buy the fat psp the first one because the universal remote only works on psp fat because the slim has no ir port or the infrared that makes the universal remote works.
Here is a list of what can you do with your psp (homebrew applications)
