Can't go wrong with Macallan. Curious why you're targeting scotch though. If you're branching out from cheap beer why not start with a good bourbon. I personally prefer bourbon to scotch, it's not nearly as snooty, tastes better, and is easier on the wallet. Check out Cedar Ridge distillery, they're just outside of Cedar Rapids, they make a seriously great bourbon, and also just started putting out a single malt (scotch) a few years ago that's pretty good and will only get better. The bourbon is available at any HyVee, the single malt isn't quite as available but by no means is hard to get.
Seconded. I gave a guy a bottle of their Malted Rye Whiskey as a housewarming gift just tonight. Excellent stuff. Their clearheart rum is also excellent.
Ironically, I have never actually gone there to drink, despite living appx 2 miles away.
