Welcome to our forum.
All of your reputable manufacturers sell through a dealer network, not direct to the consumer. As for quality, I would look into Arctic, Artesian, Bullfrog, Caldera, D1, Hot Spring, Jacuzzi, Marquis, Nordic, and Sundance. All of the above will have quality, value-minded options.
I'm also in Michigan and just got a Bullfrog A8 last fall. The prices in the area seem to be absurd according to dealers in this forum.I got an A8 delivered with cover, lifter, etc. for $9,400 total. Seems others are in the $13-15k for this.Forget about any music options with whatever tub you go with. You can get a great bluetooth setup outside the tub for like $200 vs. the $1500 they charge on the tub. Plus I've heard they are not very good quality or reliability.
