CRT tester recommendations

[TUD1]

I'm looking for a good CRT tester to test and possibly rejuvenate CRT's from the 50's to the 80's. I'm leaning towards getting a Sencore Super Mack. I've seen it demonstrated countless times watching Youtube videos and that's the one I'm most familiar with. I don't really want a Beltron - I've heard you can accidentally fry tubes if you try to rejuvenate them. What's y'all's opinion? I think my radio club downtown has a few they don't want. I'll check with them and see what they have.
