I've been with Dish since 2000 and have had the 921 (I bought that one), 622VIP, 722VIP, original Hopper, HWS and now the H3. I have had one hard drive failure on the HWS and that was aggravating. But I have had all the receivers pretty much out in the open with good air circulation and plugged into a good UPS so that probably helped a lot.
I think the UPS makes a big difference since the Hopper rarely goes down during power interruptions or outages.
