You probably can't go wrong with Harmony One or URC's line. Logitech is easier to program but not as functional or programmable as URC's line. If all you need to do is turn on your receiver, change the inputs, then Harmony is fine.
One drawback to URC is that they now went 100% dealer purchase only. So if you get stuck, you're on your own.
I've had Harmony 890, Harmony 900, and URC's MX900.
For me, MX900 wins hands down. But if you're very good with PCs, then you're better of with Harmony. It's not that MX900 is that hard to program, but it's harder than Harmony.
good luck.
+1 on the MX-900. SurfRemoteControl (talk to Mike) has the best prices. They are authorized dealers so software is not a problem.
To add to the comment above, the programming is a little harder than the Harmony line, but the URC MX remotes are much more flexible and powerful. I have had the MX-500 and MX-700. Currently have the MX-850 and MX-900.
