I may be late to the party, but I just picked up a bottle of Jim Beam "Distillers Choice" 7 year bourbon at my local Sam's Club. I'm generally a Maker's Mark, Woodford Reserve, Knob Creek kind of guy, but I tell you what, this stuff is quite good. Smooth and vanilla-ey, but with a nice oak bite. For $9.98US for 750 ml, it's a bargain.
I use regular old Jim Beam as my mixing bourbon usually, like manhattans or mint juleps and the others listed above as my neat and/or rocks bourbons, but this bottle definitely fits well into the neat and/or rocks category.
Just thought I drop this in here for anybody looking for a very serviceable and inexpensive bourbon.
