I need some advise on the Pronto's. I know that the main differences between the 2000 and 6000 are color vs b/w, the memory, and the RF control. I was wondering if anyone has these remotes and can offer whether the extra cost is worth moving up to the 6000. I was also wondering if the 2MB of memory in the 2000 is enough to be able to hold lots of icons (like tv icons) that you can download. Finally, is the RF control there to operate things like lights and automatic blinds? If anyone could address these items and talk about whether or not they like having a Pronto remote I would greatly appreciate it! Thanks!
