Among other things, customization is having the choice to have any command, macros included, on any button on the remote (not just 3), and the ability to rename up to 40 commands for each device. With the Harmonys you are letting the remote control decide how it should be used most effectively. Harmony sells their remotes on ease of programming, where Pronto and HTM sell theirs on customization. All three are absolutely great remotes, but they all have different plus and minuses. As a user you need to decide what is most important to you. For further info, go to www.remotecentral.com.

Trikos, a lot of forums don't allow links to live auctions, but I have seen it done here before so I assumed its not against the rules.
