Commercial vs retail TV what are tech differences?

The main difference between all commerical and cosnumer Plasmas are the RF immitions.The consumer and comercial versions are nowhere near the same in specs when it comes to leakage of RF.This is the big reason for difference in cost.Though tempting,stay away from commercial pieces as they will cause havoc with your gear.

For Panasonic, I second Kennyt. Consumer versions often have table stand.

If you are looking at the panasonic plasmas, the only difference is the model number.
