If you need more than 2 guys to move Plasmas and DLPs, you should consider hiring sone installers that are more than 14 years old.....

For the few large CRT TV's we sell, we have some moving straps (And of course these can be used with Plasmas and DLPs too) that are harnessed over the guys sholders so your lifting all the weight with your back instead of arms. They are awesome.... 2 guys can easily move a 40" Tube up a flight of staris in no time.... Wish I had a link for ya, but I know I've seen em at CEDIA and other trade shows.... Evidentally they were intended for movers moving Refriderators and Washer/Dryers and such...... Saw 2 guys carry a Washer and Dryer Together once....

Ah.. Heres one....
