RV Products & Services: Brands of Solar Panels

has anyone had any experience with various solar mfgs? I know that Sunsei is a top brand, but I here so many bad things about Sunforce solar, how they treat their customers and dealers that it makes it very scarey be interested in their products. I personaly experienced this first hand on how rude they were and un-willing to help. This is probably the worst company in the solar industry out there? Anyone else have any such experiences with www.sunforce.com?
