For Tenn. whiskey, Evan Williams Single Barrel Reserve. But Conne's right that there aren't that many choices, though I wouldn't go so far as to say bourbon's a million times better.
Low (call it $16-25): Makers, Elijah Craig 12, Knob Creek
Mid ($26-40ish): Wild Turkey Russell's Reserve, Elijah Craig 18, Woodford Reserve
High ($45+): Blanton's, Booker's, A.H. Hirsch
