As the PROUD owner of a Pronto and previous owner of an RC2K (which I broke when I kicked it into the fireplace watching football), I have to be honest, at the risk of taking some flack. The RC2K is better at ONE thing. Once you've memorized it you can use it without looking at it. This is something that I have not been able to do with the Pronto. That being said, the Pronto is better in every other respect, as others have attested to quite truthfully.
