Definitely one of my "one of these days" projects, though I'd much
rather use an FPGA than a CPU to handle the video. I'm tired of
how awful composite video looks on my LCD TV because of their
crappy decoding (my Bt878 TV cards from the early 2000s do a much
better job) and the latency looks awful. Expanding it out to more
analog formats would be handy to a lot of folks, I guess. What
kind of price would be palatable to people? I doubt I could get
it down below $70 in any kind of realistic quantity.
If you can come up with a converter that accepted 15.75KHz. RGB + H/V or
composite video and spoke VGA on the output - AND was able to properly
handle color aliasing (think Apple 2, Tandy CoCo, etc.), I'd pay $200 for
such a thing.
There are a number of SCART --> VGA converters out there and I own a few.
All of them have issues of one sort or another with Apple 2 video and none
can do color aliasing.

I'm thinking a guy could make a major project out
of this and use three
high speed A/D ahead of some ARM based board that could acquire the video,
scale and convert to taste and then output on HDMI. Should be able to
handle lots of legacy analog formats that way.
This exists, and works even for vector displays!
