another good example is the vast difference in price between usa and uk prices. i am about to buy a lowrenceNet kit for my small boat (instruments, fuel flow and speed sensors and interconnecting stuff) after reading the article on the mainsail site, and i can get the whole setup i need over the counter in the usa for £230 (exchange rate 1.88 - £) and once i finally tracked down the parts in the uk it was in excess of £450. also the humminbird side imaging sonar kit i saw demo'd at the nec fishing show will cost me £2000+ in the uk or 1999 dol. in the usa - its the identical kit as far as i can see and i dont object to importers making a fair profit but could someone explain the big difference? off to california in june and will buy there. i realise i will have to pay vat etc on arrival but it will still be a lot cheaper.
