If for a gym, i suggest trying to use the integrated screen for TV viewing. The integrated touchscreen and hardbutton controls work pretty well, on some newer machines (I have experience with Precor brand, at the local YMCA).
I've also used many machines that had an external monitor, with a mounted keypad. Some of the machines might be too tall for that.
Cybex may offer an external monitor mount, too.
