I don't know if you've got a screen yet but my wife bought me an electric screen 250 x 141 16:9 with remote control for christmas (SURPRISE).
The only thing is that when she bought it the sales guy didn't tell her that if it was the wrong size he could'nt change it, as it wasn't a stock item, and if I wanted a 4:3 screen it would cost £150.00 for carriage and a restocking fee???
But anyway this screen is still in the bubble wrap and box and has never been used.
It cost my wife just over £900 inc remote control, screen and wall/ceiling brackets.
So if you interested contact me and make me an offer as I would rather lose a bit of money on it than pay that salesman £150.
