I haven't priced out any of the eqs I made reference to, but the SE-9 has probably more usable features than the BBE or dbx equalizers. Just because it's old doesn't mean it's less capable, as we have all been finding out.
I've had the SE-9 for a number of years, but I can imagine that a good working one will be in the $400 range, nowadays.
