Know this is an old post, but will come up in a search. I put on the Vista Cruise model MCVICY-P within a week of purchasing the bike after a 1,000 mile day. It's robust, cheap ($22-$25), and almost invisible if mounted like I did. Really think either model will work similarly, just requires a minor amount of trimming of the foot. I mounted mine so that the thumb lever is at 6 o'clock and the foot is nested between the cable nuts. I found that when the lock is engaged and I need to roll off, my forefinger will release the lock as part of the forward roll. When the lever is not engaged, it is well out of the way below the throttle.
Trimming was done to shave the inside of the foot and very little to the two corners to narrow it just slightly so it could drop into the natural position between the cables.
