I also have a 24-700, but moved it outside into the "playroom" and moved the 21-100 into the house, that's why I added the extra storage. the reason for this change was that I have the dvr in my den with a hdmi splitter that feeds the living room and the bedroom. I have two rf remotes to control it from each room. it's my cheap-a** solution to a whole home dvr or two separate boxes. it actually works really well, BUT only with the 21-100. why? because that rear mounted rf antenna works much much better than the internal ones... yeah, I'm crazy I know it!
