I've seen a few in the local ad papers for around £80. I was interested in Sprung's psp, but I'm not sure about a UK ac adapter being compatible.

I also have a couple of people interested in having their PSPs modified, so I'd like to try one myself first. I have a good source for the ISOs...48 DVDs worth...

I can get hold of a Pandora Battery with all the necessary files on the memory stick. Once downgraded to V1.5, can I upgrade to 3.71 M33-2 firmware update 3 in one go, or do I have to go through a succession of updates one at a time?
