I got a boxed PSP Go from eBay for £92.
Boxed with instructions and N1000 official Sony carry case. Excellent condition on the box and device.
I then bought an official charger for £18 (because the cable head was damaged on the one that arrived)
Other bits purchased like a clear hardshell case, component av cable, PSP Go N340 cradle, 8gb m2 card and smart mount for DS3 pad.
What I have now is a perfect portable device thats capable of playing all PSX games with the Sony built in emulator, PSP games, homebrew and many other emulators. It can also be hooked up to TV and charges in the cradle whilst using a DS3 pad with Bluetooth. Bluetooth headphones and speakers also connect fine.
Playing through the PSP version of Bomberman 94 currently (the Turbogfx 16 version)
