It's worth highlighting the differences between Super K and Super 50, as one could be mistaken for the other in the enthusiasm for an apparent bargain more easily than with AVO 7 and 8. I've heard the Super K and AVO 7 described as "sparky's meter", with the lower-sensitivity movement supposedly being more electrically and mechanically robust. Also, anyone who's used neon testers, "standard" 10 Megohm resistance DMMs or high-resistance analogue meters in an AC electrical fitting-type environment is likely have encountered the tendency to give misleading indication due to capacitive or inductive pick-up between conductors- at least this is much more likely to give safer false positives but it can be confusingly and annoyingly misleading. A 1 kilohm per volt meter will be much less susceptible to misleading indication- I think that there are electrical-work orientated DMMs available of relatively low input resistance of perhaps 1 Megohm for just this reason.
