Check out the Throttle mate - it attaches to your little five-spoked star and works great, very easy to enable to disable. My wife and I both have them, and they help quite a bit, still not as good as cruise control, but any throttle lock will not work like cruise control.
I'll have to give these more consideration. I always have the screw very loose so it would never hang up on me at the wrong time (Murphy's Law) but sometimes you just want to stretch the old right arm and give it a break, know what I mean.
I use the cruise-mate throttle cruise assist. http://mycruisemate.com/
replaces the stock star lock. Just takes a flick of the thumb to lock and unlock throttle.
