atleast it's back in your price range.
also, on your email to them you are right about the customs cost, but the shipping would prob be a bit more (you'd have to go via UPS or fedex). another thing, i know they have to make a profit to make it worth their while to import the stuff etc, but they also get the goods at a far cheaper price than we pay for them. however your $2k price range is pretty spot on for the 4 bit kit.
personally, i'd see if they can match your $2k for the full kit and if not, get the bits from america....but shop around. there are many wings west vendors in america.
