The 880 is a great remote, and will easily work with your 622 (and pretty much any other device, too). The Harmony 676 is a great option, too. I really like the button layout, especially the "transport" buttons (fast forward, play, pause, etc..). It looks like the 676 may have been discontinued, so you may find it for a great price.
I use a Universal Remote URC-200, got it for $50 from Amazon, and it is amazingly customizable, but more difficult to set up than the Harmony remotes. But, the button layout is 1st rate, very easy to use by feel.
So, basically, the 880 is a great remote, but there are plenty of great options for a lot less $$$
