Trek, Specialized, and Giant (and others) have really good offerings in that price range. Late last year, I bought a 2010 Giant Trance X4 on clearance. I really love it, but it is also my first full suspension bike and I don't have extensive experience riding other manufacturer's comparable bikes. If you are coming from a cheap hardtail, a $1700 bike will feel magical on the trail!
I think Giant offers great value. If I were in your position, I would look at their 4-5 inch FS bikes. If most of your riding will be in FL, maybe go with 4 inches. Definitely 5 inches for the Carolinas. I can't comment on 29ers, but that may be an area worth investigating too.
You also may want to look at closeout bikes at Performance Bike and other online bike sellers. You could find something awesome, but there is definitely something to be said for riding a bike at your LBS before buying. Plus, you'll probably get free tune-ups for life if you buy local!
