FWIW I bought the ROX 5.0 this past weekend and like it a lot. I've had other basic cyclocomputers and a separate HRM, never had a cadence monitor, so there may be others that are comparable or better.
At first the ROX seemed pretty complicated, and the manual that comes in the box is like 90% how to install and 10% how to use. So I got it working but couldn't figure out how to use it. I went online and got the operations manual and it turns out to be very easy to use and well laid out. It's nice the have the HRM built in and the cadence was an eye opener as I was surprised how low my cadence was.
My close-up vision sucks and I can see everything on the display easily, even the little up and down arrows that indicate if you're above or below avg speed, etc.
