I'm in the same boat at markj. I have a 2002 Legacy that I've been using for several years. (I bought it used in 2004). It's a great bow. I'm now getting the itch to buy a new bow, but everytime I get close to doing it, I have second thoughts because I love my Legacy so much.
As far as the price on the one you found, it sounds like you're getting a great deal.
Oh, and here's a link to the Legacy description on Mathews' website:
