You could get a USA strat, or you could do what I did and get a MIM one and upgrade it (see the link in my signature for a blog on the updates I made). The guitar and upgrades cost around £650 in all, and it now seriously outperforms every american strat I've played, including a couple of ludicrously priced relics. (don't get me started!).
But as 38thBeatle said, play as many as you can and make your own choice.
HTH,
