One that has a Red OK/select button in the middle of the 4 arrow keys is even better, but is likely to be more expensive (the one pictured has grey button).

The above refers to the comcast remotes. I have looked at pictures of both, and they appear to be the same, except for the red/grey middle button, and other color differences. Why is the red one better?

Separately, regarding the 15-134, will the jp1.3 work with the "homemade" jp1 cable, or does it require a more modern updated design? And you mentioned the homemade will work if you have a "serial port". Don't you mean parallel? The instructions show a db25 connector, and the documentation discusses a parallel port.
