Purchased the BenQ SW240 today from B&H. $385, and that included shipping, a $100 visor, and a manufacturer's, 3 year warranty. It'll arrive on Thursday, Jan. 2nd. Customer Support commented that BenQ is one of the few companies that makes their own screen. Most other companies outsource them.
With the pre New Year's sale that B&H is offering, I thought about the 270. But, this one is plenty large.
