I bought the Summit Python XLS over two years ago and it is a great stand. The first one I bought developed a dimple in the frame from the leg rest. I called Summit and they sent me a brand new one in less than a week! No questions asked. I have been using that stand ever since. It climbs quickly and quietly and is very comfortable. I can't tell you the number of times I have fallen asleep in that thing. You can't go wrong with one of their products.
