I'm near Midland and I believe the dealer works out of his house. He could order one for you but his main business is calibrating.
When I was looking for my RS20 it seems like the Detroit area or Grand Rapids was the only place to see one.
Hope this saves you a trip.
Why wouldn't the JVC store locator list them or EyeMedia for that matter?
I don't know.
But, I would call them both before you make the trip to see what they have. The recession has not been kind to the AV dealers in southeast Michigan. I've found everyone more than willing to order something if you want to buy but short on new product if you want to see the latest hardware.
