Hi I am looking to spend between $500-$700 on a tv, i sit about 10 feet from where my screen will be placed. I briefly looked around and have come to the conclusion that i want to ideally get at least a 40" tv ideally with 120hz as it will be used for #1 gaming #2 computer # 3 movies the only tv that i was able to find is the Vizio E420VL http://www.amazon.com/VIZIO-E420VL-42-inch-Class-120Hz/dp/B003GDKP2Q/ref=sr_1_5?ie=UTF8&qid=1292578778&sr=8-5 or possibly the led version? I don't fully understand what the difference is between the two. Vizio M420NV http://www.amazon.com/VIZIO-M420NV-42-inch-Class-Razor/dp/B003LL4UR4/ref=sr_1_11?s=electronics&ie=UTF8&qid=1292580326&sr=1-11 I just wanted to get some advice/opinions/alternatives before i actually spend the money -- Thanks in advance!
