There was nothing carny barker about Russco tables: they were made for 24/7 broadcast use. Wow and flutter were in no way comparable to, say, a Linn Sondek, which back then was actually (hard to believe) less expensive. (Its the most overpriced TT on the market today in terms of build cost to sale ratio.) It did what it was designed to do.
There is no market today because even stations like crappic rockers that play vinyl actually copy it over to a hard drive and play off a server. For that, a Technics or any other light DJ table works fine.
Using one today would be dependent on finding new (not NOS, new as in cure date of 2008 or later) rubber drivetrain parts.
Several other similar tables such as BE existed.
