Ex: Currently use a Auto Meter Tire Guage for low pressure (0-60 psi) applications . It was a little more expensive $33.00 at Walmart , but it has a Stainless stl. casing and stem . I have used numerous other Stick Guages for higher pressure applications from Sears and Canadian Tire normally around $12-$20 buck range . The Slime product for Quads and such should be adequate though .

The one I like to use is actually a Centech digital gauge from Harbor Freight. It seems accurate com pared to my good shop gauge, but it displays the PSI to 10ths of a pound and would be more accurate than the big one in low pressures- say below 10 pounds. Actually, my big one stays on the wall. Just used the HF on volvo this afternoon when I did the fall maintenance.
