Carl, Columbus Brewing Company's Bodhi and Sierra Nevada's Torpedo are pretty much exactly what that style should aspire to be, as far as I'm concerned. They're both really balanced and the hops do what they're supposed to do by giving a refreshing bite of bitterness without overpowering all the malt flavor. I also really like Bell's Two Hearted, especially as a milder beer that's great in late summer.
Ale Asylum's Bedlam is an interesting one that I got into while living in Wisconsin. It bills itself as a "Belgian IPA" and it definitely has a lot of the fruitier colors of Belgian beers with less bitterness than you normally get on an IPA platform. It's different and really enjoyable. You can probably find better examples of Belgian IPAs, but I've never heard of that style anywhere else and I really like the concept. Fat Head Hop JuJu is another good one with a great citrus finish. I hate that I like their stuff - the brewery name and logo is sort of cartoonish and silly for my tastes, but they make really good beers. I enjoy quite a few IPAs, but I am not a fan of how they've overtaken the market.
Michael, if you read closely, you'll note that I never said variety was suffering in the craft beer market. My qualms are with the percentages. 10 years ago when I first started legally drinking, I spent most of my time at two bars that stocked between 250 and 550 beers from around the world. The variety was astonishing, and they augmented it with frequent tasting events where $10 got you a ticket to spend a few hours tasting dozens of different styles until your tongue was too pickled to continue. The styles available were vast and varied and every beer that on offer was a little different from the one next to it.
Now, I can go to those same bars today and still find plenty of variety, but where I used to be able to point to a shelf and say "Hey, I'll try something from that section!" and know that I would get something I'd never tasted before, 40% of the shelves are now stocked with IPAs because they've become the opiate of the bandwagon drinker. The neighborhood beer shop down the street from my house always has something exciting available, but I increasingly have to sift through box after box of shitty IPAs to find it. And it's not that all IPAs are even bad, but they are the easiest style for a novice brewer to produce without his mistakes being obvious and there's a huge recent surge in breweries that specialize in them and that focus on making their offering as offensive as possible in the name of IBUs, because IPA fans don't understand subtlety any better than RTJ fans do.
There are still a lot of good things happening in the craft beer world, and a lot of interesting new interpretations on old styles available. It's also nice that I can buy good beer that was made in my time zone so easily as opposed to exclusively supporting the import market, because 'Murica. But it is nonetheless disappointing to see so much shelf space and so many handles dedicated to growing the bandwagon instead of actually growing the craft.
