Query: Died after one year

I bought this model last year and it worked great. This year it would not start. The good thing is Blue Rhino honored the warrantee even though it expired a couple of weeks before that. They said that this model SV-27 had a flaw in the design of the combustion chamber which made it more likely to fail. They said the newer models (like SV3000 and SV5000) have a better design. They did send me a replacement engine (basically the entire top) which is one of the newer models. I am pleased with the support I got from them but if I was buying a new one I would not get a SV27. I would look for one of the new models.
