Which CRT tester to buy?

[jroberts500]

Hi Everybody!
I have much to post but a job is bringing way down, so, I apologize to Jamie for taking so very long. I have to find a new 1 bedroom apartment on top of everything.

I must test and possibly rejuve 3 CRT's; a '63 RCA roundie, a '72 CTC 54, and a '68 Motorola solid state. I don't know thier CRT #'s at this time. All are original tubes for each set
I wish I could buy a BK 490 as I suspect it is one of the best but I have a budget. My friend Ed Callahan used to use a BK 467 and he did not like it's performance in rejuv'n as well as his old BK 440. Can someone recommend a couple good ones for me to search for? Is a late model Heathkit a good one?
Thanks much, John
