The 922 is the newest one, and the one I would recommend, 920 is a pain with unplug replug and it can't get all the channels, the 905 is a slave to the old analog IRD and makes it hard to use or a hassle with the remotes, the 922 gets more channels and has better features, and will last longer if you buy one from NPS or Skyvision now, they are all brand new units with brand new batteries, getting a used 920 or 905 is not a good idea, unless the battery has been replaced, it lasts about 10-15 years, so a new 922 will be your best bet.
