I have a Sole - I know a few other KR's who have Sole, and did some homework shopping around, and looking at TreadmillDoctor for reviews.<br><br>
I ordered the Sole F-80, but they sent me the F-83 (one model up). It was $1499. They have a model the F-63 for $999, and I know of at least 2 KR runners who use that model for running.<br><br>
I run 50 miles per week. 15-20 are on the TM. I use it to help balance out my family time. My wife takes night classes twice a week, and the TM allows me to watch my son, and squeeze my runs in.<br><br>
I've actually gotten so that I like the TM for what it is. Softer surface, and it keeps you on pace. I use it for tempo runs, and intervals, but I also find it very refreshing to use the TM (and HR strap) for recovery runs. I find that it's easier to force myself to run slow and steady recovery runs on the TM.<br><br>
Like Sisu said. The warranty is very important. It's one of the reasons I went with the Sole, Sole has lifetime on motor, and frame, 5 years on the belt, and 2 years on the electronics (I believe).
