A google search shows 1x4 hdmi splitters are readily available.
If you live in an area of lighting strikes and power surges they may not be a good choice. I've had 2 fail at our cabin. The second failure the unit's power supply was connected to a battery backup but, at the time, the tv wasn't. During thunderstorms we have short duration of 2 & 3 second power outages. The tv would go off and on until I unplugged it. It's now on a battery backup too. This may have been the reason for the second failure. In any case I don't think the units are very robost in handling anamolies in power flucuations.
I abandon the hdmi splitter and now have the 2nd set connected via the component cables.

[/FONT] Pros: First of all, this works well. Here is my setup:
Dish VIP 922 - splitter
splitter - HP monitor (in kitchen connected w/ 75' monoprice HDMI cable)
splitter - Samsung LCD TV (in bedroom w/50' monoprice HDMI cable)
splitter - Yamaha 7.2 receiver
As only my wife and I watch TV, it didn't make too much sense to spend the money on separate dish receivers. Plus this makes it easy to leave the TV's on and go room to room (while doing chores) and still be able to watch DVR content seamlessly.
