I doubt many Mark IV FFR's are for sale at a decent used price, thats a fairly new offering. I'd give it another year or so before I'd start looking there.

For $30K, used, you will have to make some compromises as to what you want, gotta have, need, etc. More like, what will you settle for. One thing you might consider is a incomplete kit, someone started and didn't finish. Usually a very good price, BUT, man the dollars can add up fast depending on the deal, which may not be a "deal" after all when your done! Of course, if it's incomplete enough you could build it to your specs.
