Chris -
Pre-ban receivers tend to go up and down with (fill in democrat of your choice)-paranoia.
After BHO got into office, they went through the roof. I saw them for $600+
6 months ago I saw one go for $400, on NES classifieds; you can get a decent deal on them.
keep your eyes peeled on this forum, sturgewehr.com, and ar15.com.
Also, check out ctguntalk.com. Since CT also has an AWB, there is stuff up there.
Unfortunately, I think prices have begun to go up again.

But if Romney wins, prices will probably come down again.
Like I've said before. I see no value in a telescoping stock, flash hider, or bayonet lug. For me it was the threaded bbl. But now that I'm in MA and can't bring my suppressors with me, I don't really see the value in pre-ban.
Like I said. You can definitely build a fun, sexy post ban gun. This gun, while pre-ban would be perfectly MA legal if the lug was removed and a brake pinned in place.
