Go with the Kawa, just got done dealing with Kohler rep, and of course after a
summer long battle and keeeping records of the oil consumption he decided that it was my fault, go figure. Keep posting all of the horror stories about the Kohlers and maybe after they get enough bad reviews they'll figure that
maybe a little customer service will go a long way. My business was built by word of mouth, it can just as easily tear a company down.
