If you just want to get the device get it from ebay.

The global shipping program is really great for this IMO; you pre-pay any taxes due (just VAT for laptops IIRC) so you don't have to deal with extra waits or paying a ton for DHL/whoever to collect it from you. The seller ships the item to a distribution centre domestically, then ebay check it and handle the international leg.

There's a good chance you'll end up saving compared to buying locally in the UK even after paying for shipping and VAT on the whole thing. Have done it with my last couple of laptops and wouldn't hesitate to do it again.
