I've got a Type E injector which is a bit loose (as mentioned in another thread) and I'm going to take a crack at fixing it. If I can't manage to, I think I'll look for another Type E, as I have the case to the one I bought, but I thought I would also solicit opinions - given I'm a pretty smooth-faced, sensitive-skinned guy and would prefer less aggression to more, is there another type of Injector that would be particularly well-suited?
