At this point, I'd not buy the 42HL167 for the same reason I'd not buy the 42LX177 which is a superior model. I think the samsung is good, but last year almost all samsung LCD HDTV units had a connectivity problem with Sony PS3, and since I own a PS3, I'd like to know if it is safe to buy Samsung and what model. As I said in my post, I will not buy anything above the $1700 target price.
Btw, you should mention what your target price is so that people can give you suggestions. I hope that someone here can help us both.
I want to add that if you still wanna buy 42HL167, then try to find the 42LX177 which can be purchased for $1700 + tax, of course. Last weekend, my local dealer had it for $1600, but I am glad I did not buy it for the following reason (please read review a cnet):
Btw, this review is for the 52 inch model, but it is ok:

Another note is that the dealer told me that in order to purchase this model LX177 I'd have to order it and wait one week before it can get delivered. The last Toshiba I bought was like that, and I had to go to a local TV consumer advocate and have him investigate the delay to have actually my set delivered. This happened about 5 years ago.
