In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I'm old school and have always used the old compound gauges, but these new electronic gauges made by field piece or testo seem very cool. I've always used two sets of gauges because I never want the oil from R22 units to mix with oil from R410A units since they are different. How do you guys feel about that? If I went electronic, I wouldn't want to buy two because they aren't cheap.
