there is guys importing and running shops in the uk theres ASBO RC on facebook run by guy called dale clements, and also slide dynamics rc, also james who was half of soul rc runs rcboss.com which is europe based but shipping is still fast
but if you want the best prices and finding cool stuff you wont find anywhere else i use rc-art (not mart) http://rc-art.net/index_eng.php
theres an option when you go to checkout that will get them to give receipts saying the value is 10% of what it actually is so you dont get raped by customs and the shipping time is super fast there always been less than a week
