You can use a one dish solution now for both EA and WA by using a 1000.2 dish with the corresponding LNBF. I would recommend two Hoppers, one to keep at your house and one to take with you unless you don't mind unplugging and plugging it back in when you travel. Instead of dealing with the headache of calling and switching your address where ever you are or changing out the LNBF and adjusting the skew and elevation constantly I would buy a OTA USB for the Hopper and when you get into an area with different locals you would just have to scan for them. The reason I say that is because you can use and eastern or western arc dish anywhere in the US. The only issue is if you're using a WA in an EA market you will not receive locals. The OTA USB will resolve that. In my opinion you should get 2 hoppers. Say you live in an eastern market. You leave that Hopper at home recording the eastern market locals from your city. Your second hopper you take with you and while your other hopper is recording EA locals say you drive into a WA market. Plus in the OTA USB into your other hopper, scan for locals, and record those. If you get a hopper with sling that you leave at home that's connected to high speed broadband and you have good signal at home you can stream stuff from your home Hopper to wherever you are.
