Receiver question

Just wondering which receiver you folks think is more reliable, the H20-100 series, or the 700's? I've been with Direc TV about 8 or 9 years now, (am considered an A-list customer) and have had a few minor problems over the years with their equipment. That's to be expected for that length of time., but overall I've been very satisfied with their service, and customer service. Recently I ordered another HR-20 to go in a spare room because I bought a Samsung 52 in. LCD TV that I love, by the way.

When the tech was installing the HR-20 it was raining intermittently, so I didn't think anything of the fact that the H-20 700 receiver in my bedroom was losing signal. It wasn't until after the he left, and the weather cleared up, that I realized the signal wasn't coming back. I called DTV, and the tech support man stated that they were having problems with some of the 700 series receivers eternally searching for a signal, but never finding one, so he decided I just needed a new receiver. I ask him to notate that I was requesting one of the H-20 models so I could get the OTA tuner capability, as they don't offer local channels in my area.

Yesterday I got an H-20 100 series replacement. Upon trying to activate it I ran into the same problem. Not to mention that it kept screwing up when I tried to set the 720P mode. It would proceed through the menu with every other aspect ratio (including 1080i) just fine though. The CSR talked to me like I was child, and kind of ticked me off because she said in an annoyed voice that it was impossible to get a picture using an HDMI switcher. She kept telling me to use the component inputs. Excuse me, but I got a good signal using a Monoprice switcher before all this happened, and I'm not a complete electronic idiot. I have to say that she is the only rude CSR I've ever talked to all my years of dealing with DTV.

I called back, and thank goodness decided to talk directly to tech support again, who escalated my case. I received a call back from a helpful guy, who said they will send a tech out on Saturday. I realize this post is long, but my question is should I take the refurbished H20-100 they sent me, or keep my H20-700, which was working fine before? Thanks.
