This may very well be true. I emailed Sherman asking about their products, and they responded the next day and let me know they do not manufacture any products. However, I have twice sent emails to Classic2current with questions and got no reply either time. Too me, that says a lot about their support team. Might be an isolated "two times", "to one person", but I won't deal with a company like that. As for prices, I'm sure there are two qualities of panels, as there are two prices at every place you can buy them. Most likely the gauge of the steel used in the product.
