Like new PSP Slim & Lite, I bought it 2 days ago. It comes in its box and has a 12 month warranty on it (I will include the receipt of course.) I have looked over the console and have not noticed a single scratch on it. (I'll try and take better photos later if you like, but I don't have enough light for good photos without flash right now, and the flash is reflected)
I have opened the battery, but it does NOT function as a Pandora battery, it functions just like any old PSP S&L battery should, and if we're trading we can just keep our own batteries anyway.
The reason I want to trade is that it seems to have a TA-88v3 motherboard, so can't install custom firmware on it (my main reason for buying one in the first place), so in return, I want any old PSP Slim & Lite, box or no box, don't care what it looks like as long as it's decent and everything functions OK and I can install custom firmware on it, and in return you get a shiny new looking one with 12 months warranty on it :)
If you would like to trade, please let me know what your date code is (you can see mine in one of my photos, it's under the battery)
If nobody wants to trade I may sell it but I am still undecided on that, so I won't be giving a price yet.
I've put a price down as a rough estimate.
