I've seen the STG3 on ebay for like $2,700.
I've also heard that the Ref 30 has the popping problem when you switch inputs too , and that the on screen display comes up everytime you do something.
Fosgate Audionics has a pic and some stats on their new pre-pro on their web-site. It looks ok, imho. Hopefully Sherwoods new pre will be good. I think it'll be way less than the $3000 everybody else is at.
