Sencore, a long time ago used to make very good test equipment. Somewhere in the 90's I think (not sure), something changed and they became more of a marketing company. Indeed, in the mid to late 90's I got over $10K worth of Sencore gear myself. Huge mistake.
I still have a Sencore RF signal meter (analog/digital) but I need to really replace that - it is a PIA to use.
All the video calibration stuff I got rid of a long time ago (junk), except the VP401 media generator I kept (which was upgraded from a POS VP300).

The Audio analyzer I had (SP295), I sold to EJ for a really good price. So even though it was kind of a POS, he got a good deal on it - certainly worth the money.

I have looked at the Studio Six Digital stuff and it looks nice.
But I really want to get the Gold-Line TEF25 with all the extras - but that's almost $6K (I already have Gold-Line impedance meters, polarity checkers, etc..).
Studio Six Digital sure is a lot cheaper and prettier :)
