We live in Weeki Wachee (Hernando County)...moved here from Tampa about a year and a half ago. Cost of living is generally much lower here, as are the taxes, homeowners insurance, car and bike insurance, etc. We have what some may call a "McMansion", but there is plenty of good housing here in all price ranges. It all depends on what you are looking for (gated community, golf course communities, etc.). Homes where I live range from the upper 300's to well over 2 million. As I said...it all depends on what you are looking for in a home/community.
The riding around here is relatively good...well, as good as Florida gets in my opinion. There are a lot of mc riders in this area...and lots of activities as well.
Good luck with your search. I concur with the advice to find and retain a good realtor. Good luck, and hope you find your dream home!
