My wife and I were antiquing in Essex this past weekend. Right in the middle of our adventure, we saw a kayak with a "sale" sign painted on it (off of main street). Now, of course, no one can turn down a kayak sale - so off we went.
We too were thinking of adding a composite boat and we found that ERBA (www.erba.com) not only was having a sale but also were selling boats on consignment. We ended up buying a used and slightly older CD Solstice glass boat for $1100.
I believe they may have other deals as well. Also, probably mentioned here somewhere as well, North Shore Kayak in Rockport sells their leased boats at good prices in the fall - they probably have some leftovers from last year at good prices too. http://www.northshorekayak.com
Not sure if they have what you're looking for, but never hurts to ask.
Hope this helps!
