Josh,
You might want to try Clermont, which is west of Orlando. It deponds on your commute, I guess. Lots of rolling hills and clean lakes....the real estate is a bit pricey, but a hell of an investment. We moved here 5 years ago and our house has almost doubled in value.
North of us is a nice little town called Mt. Dora, very pictureque and set on a lake. It connects to the Harris chain.
There's lots of lakes to choose from, if I can help you in any way let me know. Good luck with your search....I think you'll like it down here. Check out this link to the Lake County website (both Eustis and Clermont are in Lake County) see if anything interests you.
