I can't imagine spending the $$$'s on HDTV and not going ahead & upgrading to a Dish HD package - especially since you're already with Dish. The cost delta is not that much (compared to a big HDTV) and you get a BUNCH of HD channels to enjoy. In my case, ESPN/ESPN2/Discovery in HD are worth the whole package. Not to mention HGTV & Food HD for my wife.
In Texas, assume they'd just replace your current Dish with a Dish 1000 - but I'm no expert on this - I have to have 2 dishes (2nd one for the 61.5 Sat).
