I think that once you reach a specific level with a tuner, the remainder of how well it works is up to the antenna system and the quality of the broadcast. From a personal standpoint, i would NOT bury myself financially into ANYTHING unless i was ABSOLUTELY and POSITIVELY sure first hand that it would give me what i was looking for.
Try shooting for the less expensive model and put the difference into a good outdoor antenna. You'll be better off doing this than buying a more expensive tuner and trying to make do with a lesser antenna. I bet that the "cheaper" tuner and "good" antenna will be more than enough to keep you happy.... Sean
