I started this thread because I have a pricey battery-powered pump (forget the brand) that works well but has always made me nervous about running down my battery (and then welding my starter relay shut).
The pump works fine but the built-in pressure gauge has flaked out. It's annoying to think about having to carry a gauge and the pump, and switching between the two. So that got me wondering about alternatives.
The BMW pump has a built-in gauge, which I like. The Stompump has a bicycle frame bracket that could be attached to a case (inside or out) -- I like that.
Anyway it's going to be 18 degrees F tonight so I have some time to think about it. Thanks for everyone's input.
