Summary: This is an excellent buy for the $$$ and is currently the only model of its kind (offering dual tuner OTA HD dvr capability without a subscription). I have been very pleased with its performance thus far. The tuners are great - they are better than the one that came in my TV and my reception is significantly better. I am not a big TV watcher, so it is nice to be able to watch something that I actually enjoy in the few times a week I have a chance to sit down. Also nice to keep some programs for the kids. The "pause" is a good feature if you have kids, so that when you need to go upstairs for the 10th glass of water, you will not miss the last 5 minutes of your show. Sure, there are a few bugs that will hopefully be worked out with additional software upgrades (the unit can be upgraded via an ethernet connection), but the functionality is acceptable, especially considering the price. I have not swapped out my hardrive at this time, but I understand that it is possible -- it requires opening up the box (so do at your own risk!). I should note that I live in a digital TVGOS service area - the guide feature is probably not as great for those that do not. Are there features that a $700 box has that this does not? Of course. But it is a great piece of equipment for the money.
(I do need to agree with another poster that Dish customer service is pretty atrocious - they really need to at least implement some sort of an order tracking system and get some customer service reps who even know what the product is. Thankfully, I have not had to deal with tech support, so I cannot speak for whether they are more helpful.)
