I'm in the same boat. I'm using a Logitech 890 and both my wife and I hate it's layout and feel. However, we love the RF. I just purchased the Logitech One, with a remote extender, to see how we like going back to "the old days", before we went RF. While I LOVE the layout of the Logitech One, the finickiness of the remote extenders and having to "aim" at them all the time, just isn't what we want to go back to.

So now I'm contemplating the MX810 with the Rf base station. I'll have to see what prices I can get on both, to see if the cost will be comparable to the Logitech One.

''I just purchased the Logitech One, with a remote extender''
What kind of extender? The harmony one can't do RF. I'm not sure of what you mean by that.

And about the MX-810 and base station, I think you'll have to spend more for both the remote and the extender. (remote listed 250$ vs 400$) (RF extender listed 150/250$ MRF-260/350 vs none but usually around 100$ for logitech)

Logitech harmony 890:
-bad keys layout
-bad shape
-stops charging on the craddle
-is'nt handy (always feel you'll drop it)
-has a very limitate program
Does it have any qualities???

It's just one of those IR extenders, which you aim at one of the units, it transmits the signal to another unit and that unit outputs the IR to whatever it is aiming at or the little IR diodes are affixed to.

I hate those!
You still have to point something and it's useless for multi room entertainement unless you get one in each room! (RF receiver)
I have a nextgen remote extender (RF transmitter fits AA or AAA battery and OVNI shaped IR blaster) it's cheap 50$ and does the trick but it's nothing compare to those base stations with multi outputs for separates IR emitters. (nextgen comes with only one separate emitter)

But it won't have any use when I'll get a li-ion remote!
