I've got 3. One pista with one footpad and a plastic handle in my office. One pista with one footpad and a wooden handle in the basement next to my trainer. One superpista with a wooden handle and the triangular double footpad in my garage. All 3 have had their leather washers replaced, one has had the inner plastic replaced, all 3 have had their hoses replaced for something longer/more flexible, all three have different chucks (the silca air compressor style at my office for quick changes to schrader to blow up my yoga ball when I decide - once again - to stop being lazy and sit on it instead of the chair, the garage superpista has the silca hiro screwed into a lezyne chuck with a bleeder valve, the basement has the hirame chuck). I appreciate how well they all work and how amenable they are to modifications/repairs. I know I've replaced the gauge on at least one of them, maybe 2 at this point, but the newest of them is probably 30+ years old.
