Ha! Was in a very similar position until about a year ago, when I finally succumbed and got a Megger 1741. I still have fond memories of my KT63 (particularly when the Megger starts to weigh heavy round my neck!). The only thing I didn't like about the KT63 was it didn't remember the lead null reading after power-off... and if you didn't press a button for 3 minutes, it powered off. So, so irritating when you've got the wander lead out doing an R2 test, and it times out. I got used to impulsively pressing the test button every minute or so, a habit that took me several months to get out of with the Megger (which, of course, on a Megger, pressing the test button on continuity test removes the null reading!). I sold my KT63 on to a forum member.Kewtech KT65 for last 3 years. It’s been reliable and we understand each other. I do have Megger envy building, but the KT just won’t die .
