I am looking for a new HD Receiver with a faster Blindscan & been reading about the new just announced Openbox X3 HD PVR(3) which they say has a 50,000 channel capability, versus Skybox F3, versus Skybox M3. They All seem to carry the latest: ali 3601 Main Chipset. Does anyone know what the differences of these receivers is? That is, it looks like the the Openbox X3 is the newest one, but looks like there are no venders for the X3 so far except maybe Chinese seller yojia and yojiatech.com re info. Some Youtube Videos show the Skybox M3 which looks like a smaller Receiver than the Skybox F3?? At under $100.00 each, I'm wondering which one would be the best to try out? Any comments would be much appreciated.
