I bought mine from the factory and I am located in Texas. The sales rep at Carlton arrainged to meet me halfway, as he was headed in my direction anyway. I was planning on driving to the factory to get it, thus saving money on shipping. Either way, it was cheaper than having it shipped.
Not sure about michigan sales tax laws, but you should be able to buy it tax free from the factory. That can be a very big savings. Call the factory sales folks and they can give you details about paying sales tax,(or not paying).
