Awesome thanks guys! The PS3 I'm gonna get is the Slim, not the 'Super Slim' with the sliding top, and I'm gonna get a pretty hefty one for the sake of future-proofing so like 250gb or something I'll see what they have in the store!
Thanks again, I'm gonna whack the hairdryer on and fry some circuits! I've checked my Sony account and I'm only active on the one PS3, so as long as I can get it online long enough to back up some saves i can just deactivate it later, as I don't think there's any downsides to losing the other installed stuff, right? :D
