Answered a CL ad on a 50" 1080P plasma for $300. Them not knowing the model number gave me pause...But it was hanging on their wall. Part of the ad asked to mount the new TV in its place. They were "assured" the new TV fit the mount(after an email exchange...they knew what VESA was...and both TV were the same pattern). The plasma was less than 3years old...but unsure of model.Alas. I show up. Hand them $300 take the Panny down. Mount their new TV. What were they?50ST30 coming down.JVC 55" LED LCD going up.They wanted "newer tech"..............
