I've searched the archives, and am trying to decide between the Samsung Sir-T151, the Panasonic TU-DST52, and the Zenith HDV420.......they all seem to have the same features, but am wondering if one stands out in regards to performance/reliability? Are they all going to have the same picture quality? I've read a lot about the Sammy (which is going for about 225) and the Zenith (which costs a bit more), but am not able to find anything on the net about the Panasonic (which is the brand I'm partial to). Can anyone provide any information regarding this unit? Also, given the fact that I'm looking at purchasing a discontinued model (the Sir-t151), is there a reason that I should hold off on buying one of these units b/c of near-future product releases? Just trying to make an informed purchase. Thanks in advance for your responses, Derek.
