The people that handled the sale, did so in good fashion,courtious, friendly, and very knowlegable about their product. And it was very cost effective. I have run it about 5 hours now, and seemes to be doing OK. It was a little noisy at fist but seemed to be geting quieter as I run it. The onlt thing I have bconcern about, is the in and out play the propshaft has. I guess if it fails, I will find out how good the warranty is.
