I like the efactory best. It’s reasonably priced ($200/month for dedicated desk), spacious, and they have a lot of benefits for small businesses, if you are interested in starting your own or just networking with small business owners. The local tech groups mostly meet there, so it would also be easier to go to those if that’s something you’re interested in. The efactory is part of MSU and they are really trying to build up the tech community here.

There’s a few CAST coworking spaces around the south side, but when I inquired about their desks last year it was like $450/month for a dedicated desk. They do seem really nice, but I just couldn’t justify that cost. I don’t have experience with any others, though I think there are some smaller ones around.
