I have a keystone, and several friends that have KZ products. I looked hard at the Inferno before we bought the fusion. I liked the interior of the Keystone product better, and found one in the right price with the layout we liked. If the inferno had provided that first, we'd have likely have gotten a KZ. From my friends experience, KZ has wonderful customer service, a 2 year warranty, and their products don't seem any worse or better than anything else. They have minor issues, I've had minor issues with both of my keystones. I think they are a solid product, though not top of the line (like Grand Designs etc).
