The mail advantage of these panels is that they have an expansion port & RS232 port - which allow for a lot of different uses...such as syncing different screens at the same time, LAN play, touch screen capabilities, etc. Which is why they might be priced higher.
All along my assumption was that panels would be cheaper than consumer TVs but it is actually the other way around.
But the silver lining is the quoted cost of the P42V20D which is too good to be true. Will reconfirm this price & price of 50V20 (@rpugalia) tomorrow.
Would request everyone who is interested in this to send me their mobile number on pm so that I can get in touch with them if needed.
