Any decent catalog or online store will have quality gauges. Outfits like Summit, Jegs, Longacre Racing, etc. Snap-on and Mac both have some decent lower priced gauges for less than $40. I prefer normal dial gauges but there are accurate stick type gauges. Certainly stay away from the junk at the local parts chain. There are quality digital units out there but most I've found are more spendy. There is no reason to spend more than $30 on a good quality gauge. Find a buddy that has a quality gauge you can check his gauge against yours and if there is little or no difference keep what you have.
What are you asking regarding spring loaded?
