A very high end Sony maybe - but most manufacturers have wised up to the weak dollar.
Also don't forget the keyboard will be US layout - annoying for the £ & € signs - it is solvable but clumsy.
If the OS is pre-loaded what are you going to do if your hard drive fails - you will need an international warranty.
Sales Tax varies widely by state - CA & NY are both high.
If you can reclaim the VAT on EU purchaes even high end models are going to be little difference in price.
& finally whatever you buy that is cheaper than in the UK, it will be the same price in the UK within 3 months!
That said I admit to having a US Sony SZ491N - it had a 200Gb hard drive and a faster processor before they were available in any format in the UK and it was still 30% cheaper than the highest spec UK model in the same series then available. But the value was only relative, I use photoshop and edit TV productions so the very high spec made sense. But for general use a £499 - £799 model is very adequate.
Just a small word of warning too. READ the small print because a lot of the so called offers have in very tiny writing 'After Rebate' So you end up paying the full price and sales Tax (7% in Florida 4% in North Carolina) on top. You are only likely to get a rebate if you have a US address. Then you have to photocopy the sales reciept and mail it off to whoevers giving the rebate. This can take ages.
