I am an existing 8 year customer with a Dish 500, DPP44, 3-301 and 1-625 receivers all leased. I was thinking about switch to HD. Back before my locals came up on HD, i was just going to add a wing dish at 61.5 as there would be no way to get LOS for 129 through some trees. Now that my HD locals are available(Cincinnati) i was thinking about upgrading to HD soon. Cincy HD locals are only available on 72.7 which would force Dish to upgrade me to Eastern arc and EA requires MPEG4 receivers. Anyone ever gone through this drastic of an "upgrade" with regards to equipment. I know that Dish has a limit on receiver upgrades at one time so i do not know what their position is on upgrading my entire set up to switch to HD. My last upgrade was over 2 years ago when i upgraded from a 501 to 625.
