I ordered a like-new item for half the price of a new gauge. I knew something had to be wrong with it, but I'm resourceful, so I took my chances. The gauge I received was in perfect condition, except that the needle read 3 in/Hg at rest. I knew that would result in inaccurate readings in boost, so I tinkered with it a bit. I pried on the coil just slightly until it read 0 and verified with a hand vacuum pump/gauge. Now it's perfect and has been working very well this past six months or so. As far as the quality of the gauge, I couldn't ask for more. It's very smooth and the needle doesn't catch or bounce anywhere. I would have paid full price and still been completely satisfied.
