another vote for Evan Williams. I tried it and a bottle of Old Forester and thought the Evan was a smoother sip. A very simple flavor that is obviously short-aged, but still smoother than expected. At $10.31 a fifth (including tax), I wasn't expecting to find much complexity.
I'd have to say Evan Williams as well. The problem is that its' sweetness becomes gagging once you've been drinking it hard for a good while.
Ever hear of Kentuicky Deluxe? That's "KD" to those unfortunates who drink it. Popular among hobos and broke-ass desperados, you might run across empty bottles under overpasses and such. I drank quite a few fifths and half pints back when I was broke. Now, I'm livin' it up with my old favorite, Jim Beam.
For a cheap scotch, try Clan MacGregor. It'll get you there.
