does the job - cheap and cheerful
bought the cheapest shock pump because : away from home, staying with pals and one of their bikes had no air in shock. aluminum tube seems solid enough, fittings and operation all good, (everything else is plastic, rubberised stuff). claims to go to 400psi, but I have not tried that (the application didn't require it). pressure release valve; yay. reasonably light. the gauge cover is acrylic, so consider some kind of protector to keep it from scratching if you're carrying it in the field . solid enough tho. can't argue with it at that price.
