The SMPTE standard that was finally adopted (back in the early 80's) was 10 bits at 4fSC.
The one I liked the best was the DPS Phaser (I or II). But the tektronix and Sony are good too. Those are old broadcast units that you might can find used at a good price since all that analog system equipment is obsolete now. Good luck!
Nothing comes up in a eBay search for any of those...

I see stuff like this:

A bit on the expensive side for something that may or may not work..

I bought a OEM prime image TBC/Freeze, and it seems to be picky, not sure if it's got issues with bad caps, which I suspect.. Seems to produce color bars when I first power it on, and the better VCR i have it flickers like the vertical is out of sync at times
