But that's always going to be the problem, innit! Prices might be cheaper, but if you have to slap on another 30-50 pounds shipping, the savings go out the door!
well depending on the shipping, but a opty 170 in us, is a good £50 cheaper than one in uk, and thes just the cpu, if your spending a lot on a system id say theres a few hunderd to be saved!
