I have a huge VHF only antenna and an 8 bay for UHF. I set this up to receive the low power digital ota's back when they first became available. Now that everything is up to normal high power, I get 2 dma's with a noticably better picture quality than the same channel on Dish. All network stuff I record ota. So 2 ota tuners is a big benefit.
Getting a service call would not gaurantee a K either. Plus I'd have get off work to be there. I figured after I made it to the top tier (supposedly) of customer service that they could handle this. But whatever, I'm over it. I got what I wanted.
I'll admit it, I'm a 722K fan. It works well and does what I want. Yeah its not the latest and greatest but most (if not all) of the extra stuff that even the Hopper 3 does, I don't need. 4 pictures on one screen, really, I never even watch the 2 that I have available now. 16 tuners, I've got 8 with 2 722K's, thats more than enough. Netflix, Youtube, my tv handles that.
