I have a oldish MBP, a late 2007 2.2ghz dual core 15" model. I'm interested in getting more screen real estate in the cheapest way possible until I get an imac one day, and I was thinking that would be easiest by buying an external monitor or HDTV for my laptop. I would also like to hook up game consoles to this as well. Any recommendations? Looking for both modest size and price, preferably under 30 inches. Thanks
