Anybody using the Heavy Duty series gauges? Looking at the R607T, looks alot easier to read and there is no signal amplifier to hook up.

Price: $133.55

The EV series are much easier to read in my opinion. The light thru the dial and convex lense are a big plus. I sold a lot of the old series, and switched to the new series exclusively shortly after their release.
