CRC has stores in both Ft. Walton and Destin. The Destin store is just behind Walmart to its north. The techs are very good, and the pricing I've experienced has tended to err on the low side of expected. I've met the owner in my condo building, and he is a first rate guy with a deservedly good business. He is now able to sell Apple products, and I look forward to buying Mac gear from him. Every local Mac user should get to know these folks.
The VP of our condo board is a genuine techie, with lots of money in technology in his penthouse here and his home in Atlanta. He introduced me to CRC. They do remote troubleshooting for VP's wife, whether she's in ATL or locally, and they offer this to anyone. When AppleCare runs out on my iMac, I'll use them every time I get stumped.
Best buy and MacMall may save you a trivial amount of money on the purchase or not, but CRC is worth looking into.
