I'm not sure of their distribution, but J.K's Scrumpy from Almar is good (tastes like real, fresh cider from a mill, but with booze!) and Uncle John's has grown quite a bit, doing a variety of ciders and apple infused wines. There's also Blackstar farms which I've had a few times, though I don't remember how it was anymore, and B Nektar does some cool Meads and cysers.
Woodchuck and Strongbow are easy to find of course, and while kinda too sweet for me to drink all the time, I still love them, and I know they were an intro to me into other ciders, as they hopefully will be for others.
I'm sorry, I get evangelical, but I love the Beer and Cider in Michigan
