I'm rather fond of this thing from Advance Auto. think auto Zone sells a 
similar one.

I have one in the car and another in the toolbox, and occasionally check 
them against each other and they agree. And they were purchased a good 
time part. Mom  & riend both have the same one and they are all 
consistent. That's not "accurate" or "calibrated" but a generally good 
sign. It has a nice bleed-down button, you you an sihtly overfill the 
tire, then bleed down to 1/2 psi or so.

TireRack.com sale a bunch of fancy digital ones, too.
