I have reached the conclusion that the SF-2 should be the next addition to my chain. New or used, and when, are the only questions remaining. Anyone interested in parting with theirs?

Good conclusion. I added one a few years ago and never looked back tonally. I got mine from the states from someone  on the forum here.
Never had a problem with it. My use of it is quite subtle.
