I looked closely at the Summit's when I bought a new climber this year. For the $$$, the Ameristep Non Typical Lite is the better choice. It has similar design as the Razor X5, however is $50-$75 cheaper. I REALLY like the locking straps too that lock the top piece down. It also has a bit of lumbar support. The only problem I have in this stand is that I tend to want to fall asleep in it during long sits because it is so comfortable.....
