Nearly every house in Germany has the roll downs- rolladens. They don't cost nearly as much there, probably because they are planned into the house construction. It would be great if they were more available in Fla at a relatively reasonable rate. Seems like you should get a break on ins. if you have them.
As an alternative, I've know folks who use the professionally installed window film and feel it affords some level of protection. (And they make it in lots of nicer shades than the somewhat ugly mirror reflective type.)
