Anyone have any recommendations for good testers? I see them on Sears.com for anywhere from $35 to $100. I just want a reliable one. One that I can trust. If I have to spend $100 OK, but if I don't all the better. I would not be using it much, perhaps 1-2 times per year I would imagine.

 

You can get a good one for less than $100. The one I have is a single gage, I probably would spend, a little more to buy a duel gage one.
