Nine lives. I personally think that F16 should be high on your listing with these wishes.
The budget and age of that you specify make it even more so.
With regard to second hand F16's. I still believe there is one on offer at Gulfport yachtclub which is very close to you. It belongs to Mike Crawford. Fred Metcalf was considering buying it but I never heard if he really did. Fred now sails Tiger F18 with Jennifer Lindsay so you can approach any of these and find out if it is still available.
Rick White boat is still on offer but I think that price needs some negociation. This one is in the classifieds
And otherwise, if you are up for a trip, there is a 4 year old Stealth F16 (carbon mast) on offer for 7000 USD in California. This one too is in the classified section.
I hope this helps.
