I live in Cedar Rapids, Iowa and Nolting is in Hiawatha, about 10 minutes from me. They are now the Nolting / Hinterberg headquarters.
I called because I am going to go out and visit them, to look at the Voyager and the Summit frame. They did inform me that the Voyager is being redesigned right now. They wanted to increase the quality of it but keep it at the same price point.
Just though I would let you know in case it impacts your decision, but you might want to hold out for the redesigned version. :)
