I already own a ps3 but i share it with my brother and my brother wants one to himself now, so we can play against each other and can both play at the same time instead of having to take it in turns.

But i relised it would work out cheaper if i ordered a ps3 from american because of the exchange rate.

So would buying one from america while i live in the u.k make any difference, would all english games still work, and dvds still.

isn't it region free? everything should work....everything works for me no matter what country it's from i dono abt dvd's though

Region free

games would work, you would need some kind of power converter/adapter though.

this is your only concern.

Games work fine. DVDs and Blu-rays don't.

I would personally stick with UK. I believe Sainsbury's has a deal on them at the moment- £170 or something.

But, um... How would you go about plugging it into the wall? The savings wont mean anything if you have to spend more money on power converters, and another bluray player if it won't recognize movies from your region.

PS3 games are regionfree, you have to have HDTV to use EU PS3 games on a US PS3 cause it refuses to output PAL

BluRay will be locked to region A(but all movies from Paramount, Warner and Universal are region free)

DVD is locked to Region 1

and lastly PS3 has a powersupply that supports 110-240V. I can confrim this because i live in Europe and have an US PS3

Well there you have it.  You got yourself a local already in that situation =)

Shipping and customs fees probably make it not much of a great deal (and warrantly, if something should happen, mght be a hassle). The GBP isn't at its greatest anyway.
I bought mine while I was there (by now warranty period is over), so that worked out. As mentioned above power supply isn't a problem, neither are PS3 games. PS1 games, DVDs and region-locked BR are.
