There's the Glass Onion in Kalamazoo on West Main I believe, I actually just posted a thread regarding that. I've never personally been there, and I have no idea whether they have a good selection or not. In Battle Creek ,(30 min. east of Kzoo) we have Otter's Oasis, which has a pretty basic selection, nothing special.
