I also like the DTVPal from Dish. I ordered one TR-40 ($40) and one DTVPal+ ($70?) from DTVPal.com, where I redeemed both of my government coupons. Both boxes, with S&H came to a little under $60, but I didn't have to search stores to get the products that I wanted.
If you're in KC Metro, just get two TR-40s and all you pay is S&H. The DTVPal+ is for fringe areas, like my father-in-law in Warrensburg.
