I am desperate to buy one of these two remotes and would greatly appreciate any advice/suggestions/thoughts... I'm familiar with the basics of each from the Pronto website, but can't really evaluate if the differences are significant. For example: (a) transparancy?, (b) the extra hard buttons on the TSU3000 (can they be labelled on the screen, and change function for different screens?), (c) same or different programming software, approach, etc., Personal preferences would be helpful. Thanks!
