I've had a $24 Hurricane from Performance for a couple of years that works great. It has a double-sided head with two advantages:
1. Can handle both schrader and presta without having to fiddle with adaptors. Great for pumping up kid tires. Also, seals well and quickly on both types of valves.
2. Pump head design blows off built-up pressure instantaneously when you flip the quick release. This means that a presta valve snaps shut instantly and prevents you from losing pressure.

The barrel is too short and the pressure gauge is about 4psi off (judging by a quality pressure guage I own), but overall this is a great design.
