Steve,
You really are looking at a bargain basement EDTV Plasma display... Which is perfectly fine, but most have very similar look and feel to them. I personally would think about a Best Buy or some other place where you can get a 4 year warranty on the product if you are worried about reliability.
I got a 50" Sampo plasma for just over 3 grand from Best Buy and went ahead and got the warranty since I was concerned about it making it through 4 years. Of course, if it breaks, it will be fixed or replaced - which makes it all worthwhile.
Just my thought though is that most 42" displays look pretty similar at that price and if you have seen a few that you like then go ahead and get one and you will be happy.
