My personal review:
The LC42SB45UT from sharp is amazing.
Best price by far! One better price found was for a reconditioned model for about $50.00 less, but shipping had to be added.
The picture with HD is unbelievable. We have no problems with the sound as in previouse reviews. It was so simple to set up. Had it out of box and working within 10 minutes. This is an excellent choice. The kids love it.
