I am sure E* has many installers and installation companies in the houston area. If you go though E* to get an installation you will not know who you are going to get until they show up. If you are looking to switch due to that bad D* install you have going on right now and don't want the same company to show up at your door (some companies do install both), your best bet is to open up the phone book and find a local installer. Go to their store, check out the display set up, get a feel for their know how about the subject and, if you like what you see, schedule an install. This is the only way to know who will show up at your door before they show up.
