No offense and I am glad your happy with the Suzuki and Artic Cat, but really you cant make a decision based on only owning one brand. I thought Yamaha ATVs were the best till I got a Honda and then thought Honda was Great till I got a Polaris. Almost all the quads makers have reliable engines and drive trains. I have owned several brands and Polaris is by far the best riding quad and durable quad. The components are much larger, they have a heavier drive and by far are just less complicated. They pretty much are like farm machinery. The 400 or 500 Sportsman would be my suggestion. Stay away from the twins. Also pre 2006 Polaris are built really good. They have like all manufactures cheapened and lightened them up now to keep the price down.
