+1. There are definitely good deals to be had out there. My luck with GC has been mixed. Often times, they are overpriced for the condition that a lot of gear shows up in (ie. beaten to hell). Sometimes you luck out, sometimes you don't. My advice is to keep a very close eye on the TB classifieds. On any given day, you never know what kind of Spector goodness will turn up.
I can't remember what your budget was but you may want to take a closer look at the CRFMs, Euro4s, and possibly Rebops (if you prefer a bolt on and a less curvaceous body). Besides the used Fortes,
I think Euros are the other best-kept-secret in the Spector lineup. They give you immense bang for your buck, no question.
That said, SAS is unrelenting and being patient is really hard. Your Spector(s) is/are out there. It just may take a bit of legwork to find her/them. Note, I said Spectors, plural. It's hard to stop at just one. Trust me on this.
