Just a note to the folks who are within the territory they serve (as installers dispatched by DISH Network). My initial install was on 08/11/2007, and I upgraded to HD a month later (never expected my SD TV to die, or I would have gone HD from the outset). In both cases, these folks were nothing less than 100% professional. Courteous, prompt, both installers knew exactly what they were doing, and they completed the job (in both cases) in less than an hour. You might not have a choice of which installers are dispatched in your area, but if you do, ask for these guys. No - I have no affiliation with them at all. Just wanted to pass along my comments.
