I saw a Mitsubishi WT-A42 at Best Buy today, and was impressed with it's small size. I've done a couple of searches here and there, but I can't seem to find much information about this model at all, other than it's a Best Buy "exclusive", and is missing a couple of features from the Mitsu WT-42311. Is this a good buy? I've got a few hundred in gift certs at BB, so that's why I'm looking there. In particular, what are the missing features, and how critical are they? And how does this set stack up to the Sony KP-46WT500?
