I've got an installer coming by on Saturday to install EA and I was wondering if it is possible for me to keep my old dish when they replace the old one. I don't want to rip the installer off or anything like that, I would be willing to pay for it if it was available at a decent price. Or, do you think that they would be willing to just give it to me? I would provide a decent tip to the installer if he would give me the old dish. What is the best way to go about this?
