I paid £150 for a cased (1980 plastic case British HyScore) with extra barrel, silencer and the tools in good nick (not mint but close) and now think it was a bargain - these HyScores are much rarer than the USA 1947 style model 800 (which I have a boxed one of) so will go up in value at a greater rate.
Compare the prices in The Blue Book (yeah they are American but still reflect relative values).
I too would like to get a Sportster (shorter barrel).
