I need help from you experts here, I am new...so be nice.

Hi all, I have a question for all you guys. Is there a good UNIVERSAL remote I can get so that I can get rid of the 4 I am using?

I have a new DirecTV receiver (with the locals in HD, is that an H10 or the H20)?
I have a Directivo R10
I have a Hitatchi Rear Projection HD TV
And I have a Toshiba Surround Sound system

I use the TV remote to set the input (You know, Input 1 for the HD receiver, Input 2 for the XBOX 360, Input 3 for the Tivo, etc). Then, depending on which input I am on, I need the remote for that device.

I was looking at some universal remotes (with touch screens) from Sony, but I have no idea if they are compatible with Directv stuff. Can anyone out there give me any suggestions?

Rick

P.S. I was looking at the Sony RM-AX4000. Others have recomended a Harmony 688 or a Pronto tsu3000. Any suggestions?
