I've had the same thoughts buying from the U.K. but ended up getting the Festool HKC at a great price from Axminster, I did not have to pay any import fees with the,, I assume it was in the shipping costs. Though at the time Festool USA did not have the HKC for warranty purposes, they had me list the tool on their site by serial number on the TS55REQ listing and assured me it is covered if there is an issue. However, if I had to re wire the kit, it would obviously be voided. The nice thing with the cordless tools, the tool itself should be fine, it's the charger that would be the problem I should think. Regardless, you have a really good point and before I dropped coin, I sure would want to know too!
