There are many great areas as per the advice already given. It really depends on what you want the neighborhood to look like, e.g., new construction or resale, larger lots, country "feel", near Tampa Bay, Master Planned Communities, etc.
I suggest you interview some Realtors and tell them what the specific criteria you are looking for and go from there.
A good real estate professional will be able to match you with "desirable options" but it will require a little more information.
When dealing with a person or families happiness it helps to have more specific criteria.
Do you have children?
Proximity to work?
Desirable square footage?
Golf, tennis, fitness center
Distance from beach?
Even if these are not issues for you presently, they very likely will be for the buyer of the future and therefore should be considerations today.

I find the Feathersound area to be a real winner. It is a beautiful community with homes in your price range. It is located at the gateway where I-275 goes east to Tampa and south to St. Pete. You would be only minutes from the beaches and a hop skip and jump to Tampa Airport . Let me know if I can help you find a home in that neighborhood. Jo-Ann 727-692-0241

There are a lot of great locations for that price range. Apollo Beach, Lithia, Brandon, Riverview are all close to the Interstate and now is a super time to buy.
