Old Forester 100 proof, Wild Turkey 101, Knob Creek, Even Williams Bottled In Bond (White Label). A fellow on YouTube (Blind Whiskey Reviews) recently did a blind comparison of inexpensive, available bourbons, and Old Forester 100 proof came out on top and I agree. I have to admit to having more Wild Turkey products on hand at the moment.

ps Old Grand Dad 100 proof and 114 proof are both real good and inexpensive.
