I find this very funny. As someone who lives in the UK I've been used to the fact that some parts needed to be ordered from the USA as you just such a greater range of options than we have. Obviously things are changing. I still think you probably have a greater range but the situation is vastly improved since internet shopping really took off. Cat-Ears AirStreamz is one example - I would have had to order from the US not so long ago but someone is now selling them through Amazon UK.
I heard one of the Wiggle bosses on the radio a few years back. Interestingly they were just a small LBS who got together with a web designer to make an online shop - a case of being in the right place at the right time. Others such as Ribble have been around for long before the interweb but seem to have made the transition successfully. Another old favourite, Parker International, seems to have gone the way of the dodo.
