we have had T600, T800, T660 and two T2000. There is nothing wrong with the T2000....it is huge inside compared to the others. I don't like that I need to have the seat way forward to reach the pedals....I am 5' 9". It doesn't have the visibility of the others because it is so wide. All that plastic on the inside makes for lost of shakes and rattles. Nothing wrong with it but it is my least favorite.
