I sold 2 650's with casefeed systems for a total of just over 3K the summer after Sandy Hook. ALL Dillon reloading equipment was going for well over retail. One guy that bought my 650 in 223 had a good stash of components and said he would recover the cost of the press in one day. Probably taking a few breaks in-between loading sessions, too.
Having 3K in-hand, I ordered 2 new 1050's (With Carbide rifle dies), along with 2 650's for 2 friends. We were told by Cassie at Graf and Sons that it would take several months to get them. One friend had just gone through a year of Chemo, and later that day while driving home I was thinking it would be nice to find a press somewhere for him to use. My cell phone rang, and it was Cassie. She said "a truckload of stuff we ordered for stock just arrived from Dillon, and the presses you want are on it, all four!".
So yes, the presses were at a premium at that time, and are probably worth 80+ percent of the new value, right now.
