The A.C.T Commercial 10 is a solid machine with excellent features but I'm not sure the bigger touchscreen is worth the extra money you will pay over the Commercial 7.
Technology is becoming a bigger an bigger part of our everyday lives. NordicTrack embraced this fact several years ago introducing touchscreen models earlier than any other manufacturer. Unfortunately they really didn't have the technology ready to go when they introduced it. It has now improved to the point where it is acceptable for the average consumer. This machine gives you great features, solid quality and a good warranty. They provide really good value.
