My current pump is one of the performance house brand jobs... but when I went looking for parts, all I found were scathing reviews. It tends to eat presta valves a little and as I mentioned, it's a three handed job now to keep the head on the presta valve and pump at the same time. Not tenable.

The Lezyne pumps look good but some of the review comments indicate maybe it's not for me. People gripe that the Joe Blow pumps are sometimes hard to attach with a good connection on presta valves. I'm leaning Silca I think, but I can't find anything much about them besides "they last forever" which is obviously a good thing. Feature wise, they seem to be nearly ideal.
