I only endorsed the 667, well, because I have one... it's also got a nifty transistor tester you can use to match Hfe for audio amps. I have used it to match small signal complementary pairs of PNP and NPN transistors for complementary symmetry audio amps to good effect.
I also have a TV7 for the old stuff, which was always my go-to tester until I got into fixing colour televisions.
I have no idea the dollar value of either, I paid $70 for the TV-7 in about 1994, and got the 667 for free from a relative who bought it at a garage sale for me.
