I am in need of a quick decision. I can either get a refurb 1604 or a near new 1802 for the same price. Is there any one or two things that make one stand out from the other? I know the 1802 has pre-outs but does it have all the decoding the 1604 has and is that really important. It is about 60/40 movies to music if that helps at all. Thanks!!
