I have to ask the same question, why are you replacing the best analog meter ever built? When I first started in aviation in 1969 the 260 was the top of the line meter and priced that way. I replaced my Tripplet 601 with a Fluke 77 about 35 years ago only because the Tripplet was sent in for calibration and came back BER the Fluke is still working great today. My vote is Fluke meter!
