I bought two HDTV online but not from amazon. One from buy.com (42" Samsung plasma) and another from 6ave.com (46" Panasonic plasma). Both were safely delivered.
They were shipped by special carrier, not the regular UPS or Fedex. I’m sure these carriers are trained how to handle delicate items. When I got mine, they called me twice. A few hours before the driver called and asked if I will be available at home to accept the tv (he gave time frame). Then he called me again few minutes before arriving. They use a big truck (was 26 feet or bigger.)
You will get similar service when you order heavy household items from local stores such as refrigerator, washing machine/dryer etc.
