I have been using a Harmony 525 for about 18 months and it does a pretty good job overall. The only niggles I have is that we tend to use our sky box to change channels as we find the numbers on the 525 not that easy to select. Another issue is the up/down/left/right and especially the ok/select button is awkward to use - eg sometimes it takes quite a few presses to select an option on a dvd using the middle select button as it isnt very responsive. Soooooooo......... which of the more expensive options have (I guess I would call ) more responsive buttons???????
