I have a Michelin dial guage, works very well, holds the reading til you clear it, decided to get a decent one some years back when I discovered the handling problems I was having were due to my then stick guage being out hugely, showing 28 when really the pressure was 18...
I have a dial type gauge that is absolutely accurate. It is a Polyair gauge that I got when I had some Polyair air bags fitted to a previous vehicle. These air bags are US made so they should be easy to find so you can get the gauge if need be.
Digital for the past few years. Had a dial one before that and it broke from bouncing around in the truck. Figured digital will hold together, just never been sure of the accuracy.
Used those stick type most farther in the past, but like Jondalar suggests, you can't trust those much. Maybe real good one kept in a airtight storage tube might be okay, and handled carefully.
My digital gauge is rather large and cumbersome, compared to what I've seen available now; another reason for not getting a new or better dial is I don't know of any with a light built-in. Wal-mart has them on a keychain, or a little larger with LED light added. Been thinking of getting a new one since the battery is going to fail in the old one any time now.
Just searched the 'net and see a lot of changes in tire gauges since last I looked. Unfortunately, good digitals can still be higher priced than dials.
I've got a stick gauge that is virtually worthless, in large part because the red writing is completely worn off the white stick. I put various marks on it myself over the years, but most of the time I can't remember what the marks indicate (that and I never seem to have my glasses when I'm doing the tire thing).
My parents are weird. They buy me "car stuff" every year for xmas so I have all three. Usually I use the dial for my car though cuz I have no idea where I put the digital gauge. I use the stick for my bike because it's light, easy & cheap and it works better for higher pressures (since it's not very accurate, plus I think my dial only goes up to around 50psi & my bike tires are inflated to 80).
BIG Kudo's to MCN for doing this. If you are a motorcyclist, you BETTER have a subscription to the Mag. They are the "consumer reports" of motorcycing. No ads, no "fluff" reviews. Great writing and honest reporting.
I had a buddy that owned a dirtbike race shop a few years back, and I was able to pick up a nice Snap-On dial gauge for about 20 bucks, it seems to be much more substantial than some of the dial guages I have seen at the autoparts store, and it seems to have a larger more finely detailed dial, you can get PSIs within about .25 PSI if you want.
