I, too, have a DMM916 and I love it - built like a tank. Proper meter.
Ah yes - I've seen that one. I must admit that I was surprised the venerable AD536 was still in production, given the range of decent alternatives available today, but I guess the demand must still be there. It was no slouch for its time - there's one in my old HP 3468A - selected and burnt-in before fitting. That's a 300,000-count meter that claims 0.26% best-case on AC, though in practice, HP (and Fluke) specifications tend to be extremely conservative. A shame the 3468A doesn't do dB or AC+DC, but still, a lovely meter.
The Tek meters were made by APPA Tech for Tek - there's a bit of discussion about them here: http://www.vintage-radio.net/forum/showt...hp?t=98243 - I admit that I've not got around to using it much, though perhaps I will once I've calibrated it. I use a Fluke 87V for most things - a nice solid meter, though somewhat pricey for the feature-set if buying new.
