I need some advice from the experts here on which set to go with, the Mits. 65413 or the 613. I know that with the 613 I would be getting the integrated tuner as well as the firewire, however I am trying to justify that for the extra $500-600. I am just starting my HT and will be needing new speakers as well. The extra cash would go to the speakers, otherwise it will be awhile if I go with the 613. I guess my biggest question is, will I really need the tuner or will I be just as well off (or better) with an external tuner? Also, I currently have standard cable and am looking into a change, possibly satellite. Will the internal tuner work for HD with satellite, or would I need their tuner anyway? Thanks for any help for a newbie.
