I looked at both the tensor and the alpine tensor, they both felt the same to me. I ended up with the alpine for the higher insulation value.
The $120 one I believe is the older version with the older air valves that were supposed to be slower to inflate/deflate. I believe the new version of the insulated tensor is around $150-$160
