Lucky for you it looks like your locals come from 61.5, which unfortunately means a second dish pointed east to tie in with your existing dish. If your nice enough you perhaps could talk the installer into a 1000.4 EA dish which would cover everything you need assuming if you upgrade to HD that you aren't keeping any other standard definition receivers. If all you have is a 625 and you are replacing that receiver you could do that. Standard definition receivers won't work on Eastern Arc.
As an installer though, dish likes to create work orders for existing customers calling for a second dish, so the work order will more than likely call for a second dish. Like I said though, if your nice to the installer you could just try and tell them you'd prefer only 1 dish. That is assuming that you have LOS for a 1000.4. It comes in to the left of what your existing dish points. (around 150 azimuth). I'm here in the Springfield market and our locals come from 77, so just about every install for existing customers calls for a 1000.2 dish and a 77 wing dish. New customers all get 1000.4 dishes on work orders though.
If the installer tells you he can only do what's on the work order you may have to politely be firm and ask him to modify the work order, explaining you really don't want 2 dishes. Worse case, call dish yourself and explain the situation and have them modify it. Some installers (like me) are happy to do all they can to please the customer as long as you aren't unreasonable. Some don't want to stray from the work order because they don't want the hassle of modifying the work order. Keep in mind that the signal to the EA for 61.5 also comes in pretty low, so if you have a lot of trees to the left of your dish it may not be feasible.
And again, if you have any other SD receivers that will be remaining you will have to keep 110/119 and go with a 61.5 wing dish.
