Topeak Joe Blow (the yellow one)works for me. I have one at my shop/office where most of my bikes are and one at home. I have had both for a few years and they work well. If I am traveling , one of the comes with the bike. My only complaint is that the gage is low , but it has limiter tabs that you can set for the right pressure reading. I got them when REI was having a sale . I had a cheapie previously and it failed.
