I've been holding out buying the Sony AC-3 Rcvr ($250 at Tweeter's) because I want the next generation with built in TiVo/Replay. However, is it more wise to buy them seperately? I prefer Sony products and can access a Sony store fairly quickly. Anybody know which units are the best? Sony Sat Receiver w/ AC-3 and Sony?? TiVo or Replay products. Who's putting out these services? Does'nt DirecTV have this capablity and can add it to upgrade subscription services?
