Loud buzz when on, great picture with regular antenna, etc...
0 for a 42 inch Samsung Plasma (even though it's only 720p) is pretty fantastic. That being said here's a little more info after 3 days of using the tv.

When the tv is on there is a very loud noticeable buzz. Luckily the tv speakers are very loud and can over-power this buzzing. However if for some reason you are listening to something with a low volume, you're gonna hear the buzzing. I often have the volume low either because my child is sleeping or because I'm trying to sleep, so this isn't the greatest match for me.

The picture with a regular antenna on an HD basic tv feed is awesome. Looks great. Better than my 46 inch Toshiba 1080i LCD. (Oddly enough, my LCD buzzes when it's off, not on, so go figure.)

When running a PS3 via HDMI cable, either playing a game or watching a blu-ray, not the best picture, but this tv has a lot of options for tweaking the picture. Dark images seem to be too dark and brights, too bright. But there is a "game mode" and "movie Mode". Great sound though.

So far not bad. Stylish design. Thin frame. Light-weight. Lots of tweaking options. 0 for a brand name HDTV in the 40 inch range is very good. This makes a great auxilary tv (I'm using mine in the bedroom) and decent main Tv. Let's just hope it lasts a long time.

Great Purchase
I agree with most post this TV is a great deal for the money the only down fall is the stand and the screws!!!! Was the biggest pain to put together and like they said some are still not in all the way. I will be looking for a wall mount i think for this. Also does the remote not light up my other samsung remote has a button which lights up the channel and volume button etc, but could not find it on this one. Overall great TV very pleased!!!

AMAZED
WOW Love, love love it!!!!! what a great picture. can't believe the price. All went well with shipping, and the tv itself is fantastic.

Good TV but mind the screws!!
I purchased this set 2 weeks ago and really happy with the TV and price.
The picture looked astonishing when i watched Star-Trek on blu ray last night. The set has got decent audio for a Television.
Only reason iam giving it a 4 rating is because of the screws!! Like one reviewer pointed out... the screws that come with the set do not seem to be the right size. They just seem one size bigger and though i got them in alright...my screwdriver (and probably the screws) is almost ruined. Iam pretty sure i would need to get newer screws if i need to re-assemble the set.

Great picture quality ....minimum bells whistles
Okay for a 0 42 plasma its not fair to expect the world but I would most important is picture quality and it does great. I remember seeing other reviews that also said its comparable to other 1080p tvs and I would usually laugh at them for not being able to discern the difference. Now that I have experienced it firsthand I can say the same thing.
Few bits to note. Only three picture modes standard dynamic and movie. Never a fan of internal speakers and having trouble using antenna as source and external audio source via analag output (l/r RCA's) It appears that it may only be for a component video source that allow that. Built in tuner has grabbed all the locals but one hd (fox). I like the favorites list button. You can toggle through all the channels on your list with one button. Sounds like channel up down button but easy way to create shorter list.

Havent gone through the setup menu to review burn in features pixel shift scrolling etc. but read about some unique features that year old k Panny plasma doesnt have. Auto Protection can have a screen saver kick in after 20 min 30 min of same image on screen.It also has an Eco-sensor to adjust brightness based on surroundings.
So only true gripe is hdmi source does not allow analog audio. Also wished it had analog audio out to send to stereo receiver.
