I was tired of waiting for the concept 2 and don’t like the noise from concept 2 either. I bought a Echelon® Smart Rower $799.99 after 20% coupon at Bed Bath and Beyond.
Delivered after 5 days from Chino, CA. The machine is virtually silent. Very sturdy and well-built machine.
Switching the level of resistance is at your fingertip.
I know there are many fans of concept 2 here. I am just posting a good alternative.
