Not even Christmas can push as many HDTVs out the door as the Super Bowl, but as more people flood into their local big box stores, the percentage of people buying the wrong gear skyrockets. So before you drop three paychecks on that mammoth display, make sure you aren't falling into one of these common traps.

"Gimme the hugest set you have"

The wow-factor of a 60-inch TV is undeniable, but the crappy experience you get from watching a huge 720p set from 4-feet away can make you regret your purchase. Even 1080p sets can look like crap if you sit too close, so check out one of the many charts out there on the web and bust out the tape measure to find out your optimal set up. If you're going to be sitting close, you might be able to save some dough buying a 720p set instead of the more expensive 1080p model.
