I am not a huge IPA drinker, but there are a few i like, including the DFH beers. Founders brewery out of Michigan makes a 12% IPA called the Devil Dancer, which is definitely worth trying.
My current favorite beers are: (this changes about every month)
Left Hand Milk Stout
Founders Porter
Bell's Porter
Rogue Dead Guy Ale
Stone Smoked Porter
Mac and Jacks (which i cant get, since its pretty much only available in the upper northwest around Seattle)
Goose Island Nut Brown Ale
