Don't know about Michigan, but there is a distributer in Ohio called Mainline. 740-852-9733 A sales rep who may service your area is Paul 614-361-5343. He may be able to bring you a unit to Demo.
I wish their dealer network was better in this area. I am half afraid to buy one as it is so hard to contact anyone. Mainline is nearly impossible to get a hold of. What if you have a breakdown, will you ever get a part. I think they are likely a great product, and may take the plunge anyway.
I got mine from Oakland Lawn & Garden in Waterford, Michigan. They were real nice to deal with and loaned me their floor model to use for almost a week untill the one I ordered came in. I can't find their number right now, but I'll post it if I can find it. Otherwise try information, they're on Frembes road.
