I bought he Yamaha rx a2010 a few months ago at best buy almost the same deal as you. First off this is a great receiver. The sound is incredible, I am coming from an onkyo TX NR 807 that had several HDMI boards replaced over two years. I also have the harmony one, you may need the original Yamaha remote to learn some commands. It worked when I first set up the harmony, but was missing some important commands.. If you go to remotes..com they have it now for $139 much more then the $99 I paid at the time. The Yamaha remote is big has a ton of buttons and comes in handy from time to time..
I see this may be taking you over your budget, but like myself... We SCORED on this receiver. Make the extra small investment and you will be very satisfied.
You may want to look at the mini remote that came with it I think it was 10 bucks more.. Even look at the a3010 remote which is back lite.. Good luck
