In addition to the Sencore CR70, there are also several B&K models (467, 470, 480, and 490) that are decent. The 467 and 490 have three seperate meters for better evaluation of color CRT's. The 470 and 480 models have a single meter and a knob to select between R, G, and B color guns. The models that I mentioned also have a decent rejuvenate function that will be less likely to harm the CRT than older testers. These testers cost a lot of money when new; but, can now be obtained cheaply if you look hard enough.
If all you want to do is evaluate the condition of older B&W tubes; then, pick up an older B&K tester from the '50's or '60's. The blue cased 465 is a good tester for testing B&W and older color CRT's; but, the rejuvenate function is rather crude and will often do more harm than good when attempting to rejuvenate a weak CRT. The older CRT testers sell for next to nothing and are often free. My first CRT tester, a freebie from a shop who no longer used it, was a B&K 465 (early '90's).
