Winnebago, Schwintek In-Wall Slide-Out system - Problems ??

Schwintek seems to be taking over the market. The wife and I are looking for our next coach and I am happy to say at least 2 of our choices aren't using them yet. The Newmar 3709 and the Excursion 38K. I wanted to stay under the 200K price range but it seems that if I do, I'll have to accept Schwintck or something equivalent. Being a few thousand miles for home with a broken slide is not the stress I need in my life now.
