The great thing about the Indy based Silica is that they support the pumps made 30 or more years ago. In fact, the head they make for the floor pumps--which is a durable elastomer inside the brass chuck is a great improvement over the traditional rubber gasket which always elongated (and hissed) after a few months of use. I have a regular pista bought in '81 and a super pista from '86 and both work like new or better. I'd buy again if I lost them or they were stolen.
Their "other" stuff is expensive sure, but i buy it sometimes. When you pay unsubsidized heath insurance and full price college tuition--as I do--it's really pocket change in relation and I don't worry about it. Same thing for my woodworking--I buy some luxury tools I don't really need, but it's fun for me and what else am I gonna spend my money on?
