I got a power adaptor from Argos - it was about £8, catalogue number 982/9701. It has a voltage selector, interchangeable jacks (the smallest one fits the GP2X), and switchable polarity by rotating the jack 180 degrees before plugging it in. Seems to work fine - rated 1200mA. Though I'm not sure how seriously you need to take the current ratings - presumably the adaptor's true limitation is power (= voltage * current), so this adaptor can deliver 12V*1.2A = 14.4W of power, which amounts to a maximum current of over 4A at the 3V setting.
They have another model which is listed at about £12 I think, but in-store seemed to be only £9-£10, maybe it was on offer. It was rated 2500mA, but didn't have the high voltages, so it's essentially the same thing really!
The voltage selector has 3V, which works for the GP2X although the manual suggests 3.3V. The next voltage up is 4.5V which is probably too high. I taped over the selector switch to stop it getting changed by accident!
I'm a little unclear whether it's OK to plug it into the mains while you still have batteries in it - I think the manual suggested you shouldn't do that. If that's what the manual says, I guess it's a pretty safe bet the GP2X doesn't protect the batteries against being charged from the DC input, but it's also not a proper charger, so perhaps they might overheat. Does anybody know more about this? So far I'm taking the batteries out when using the DC input, but it's getting tedious.
I got my 2300mAh batteries from www.scan.co.uk, piggy-backed on another order - they're very cheap there, and not branded, but the lifespan seems OK (I haven't run them out yet so can't say for sure how long they last). The delivery charge is huge though, so it's only worth ordering there if you're buying serious computer equipment too.
I noticed a Wiki page about accessories:

Maybe it would be useful to list confirmed sources for some of this stuff in various countries? Somebody already pointed out that you can buy PSP cases in Woolworths that fit the GP2X, which would be really useful information to have there (especially if you can point to the exact model).
