Are the 1:18 scale sun star models difficult to get hold of in the UK. I know you can get them from America for $29.99 but with all the hassle with postage and import tax(if any) whats the final price. I came across a model shop near me with 5 sun star models? The owner said he usually carries the BTTF model but he was sold out. I haven't seen them anywhere else. Whats the usual price of these in the UK? James
