I'm looking for a accurate 30psi boost gauge and considering full sweep ,but is it worth the $$?

It was worth it to me if only because the stock gauge is defective and rather than install a new one every year I would rather pay more for one that will last without the pointer drifting. As for accuracy electrical gauges aren't any more accurate than the bourdon tube models, they are just more repeatable as there is no linkage that drifts over time & use. Alot of industrial pressure gauges have a zero adjustment screw so you can re-zero the gauge. Well these cheap $5 Autometer's don't have this feature which is why so many people complain that their gauge rests at 2 psi or vacuum with the engine off. At least the full sweep electrical gauges re-zero themselves everytime they are powered up.

Apexi uses a similar pressure transducer that Greddy, Autometer and alot of others use. They aren't as acurate as a good mechanical gauge but they are close enough.
