I'm up for one when they come into stock. Although not ignorant of electronics, I don't possess the in-depth knowledge of valves needed to fly anything more demanding than Orange's offering. Plus I have lots of valves, both in and out of amps, that require a quick assessment.

Old valve testers doesn't needed electronics knowledge to work, you just match the letters and numbers to the chart and follow the instructions. Its kind of like programming your telly with the remote with lots of buttons, vs using the few buttons on the front.
