Hi, my 3 boys all want a psp for xmas so looking for 3 in good condition preferably with firmware that can be changed easily, ie 1.50 or one of the oe's. I prefer to use these as opposed to homebrew. Would also like to know what cheapest prices for these are new in shops etc. Dont care if they are slims or not as long as good con and work well. Thanks for any replies.
