I"ve got a Topeak Mini Blaster G. I paid Road Morph price form the LBS because I was in a bind or I would have gone online. Anywho... thing has a gauge and has double pump action which mean you pump air on both strokes. Gets up to 60 psi easily, but after that, I pretty much have to get my body behind the thing since my puny arms and no arm strength do no good. But I can get up to 110 and start huffing and puffing up to 120. My buddy needed it today on our commute and he got up to 80 psi before he needed to put a little more effort into it. Neither of us had issues with the seal or damage to the valve stem. I've read the gauge isn't the most accurate, but who cares. As long as I can get above 90 psi, I'm happy.

Even though I"ve got prestas on the road bike, I carry presta/schrader adapters and a little schrader extender hose just in case. On the mountain bike, my old POS x-mart pump could maybe get to 20 psi before it was done and getting hot.
