Vacuum gage suggestions.

We are in the process of hooking up a sap puller on our 275 tap bush. Would like to know what guys are doing for a gauge. I was at dominion and grimm today but was afraid to even ask what their price was.

Bascoms Maple Farm sells liquid filled guages for about $20. We have one hooked up to the booster up in the orchard - no problems.
