I am looking for a new desk chair because bits of plastic are falling out of mine and the pneumatic piston messed up. My budget is 200 max but I would like to go lower. The only requirements are that it will last and have arm rests. What would be my best option? Chairs I have looked at so far and liked. http://www.amazon.com/Ergonomic-Off...4?ie=UTF8&s=home-garden&qid=1248147733&sr=8-4 http://www.amazon.com/Alera-NI41CS1...UTF8&s=office-products&qid=1248147927&sr=8-30 http://www.amazon.com/Super-Mesh-Chair-Headrest-Back/dp/B000NGWSXI/ref=pd_bxgy_op_img_b http://www.amazon.com/B8601-Executi...UTF8&s=office-products&qid=1248147900&sr=8-12 http://www.amazon.com/Executive-Bla...=UTF8&s=office-products&qid=1248156262&sr=8-6 Any ideas? Is there a better place than amazon to get desk chairs?
