Digital Tyre pressure gauges

[Stealer Of Souls]

I'm gonna get poked for asking. But I'm looking for anyone that can get a good digital pressure gauge on the cheap.
I've located one group (amimports.co.nz) that sells a race gauge accurate to .1psi for $165 (or on TM for $140).
I don't need something that hardcore. But I do like the digital gauges and would like one that is decent. Are the other gauges on their site going to be good. I usually find you get what you pay for, so a $20 gauge will last for $20 worth of use, and it's normally worth going for "the model up".

I can do you one through work for $30 accurate to .1psi and has a 12 month warranty, hows that
