Why not just call Dish and get one leased? I own my VIP622, but even though I bought it to avoid a contract, I've still been a Dish subscriber for 5 years. My contract would have been up now anyway. I really didn't gain anything by purchasing outright. I STILL pay ALL the same fee's Dish charges to both leased or owned, so why bother?
Just some things to think about if you haven't done all the research as of yet. I repeat, you gain NO advantage by purchasing this receiver. The only true remaining valid reason to purchase, would be if you were already at their receiver "limit", and you wanted one more.
