That was my problem too. Lots of 58mm tampers, none till last weekend for 49 mm. I think I have one of the prototype models, but asked the guy before posting here he ships worldwide. I know nothing about overseas shipping prices, it can easily douple the original price, but it still cost less than most 58mm precision tampers, and those usually needs tools to adjust, or they have a stepped mechanism. This one is stepless and needs no tool to adjust.
