Hello, I am purchasing a new tv in about a week and need some opinions from some experienced people. I dont know to much about anything when it comes to this new technology with tv. The two tv's the guy at best buy recommended for me was the Sony - 50" Grand WEGA SXRD Digital-Cable-Ready Rear-Projection HDTV - Silver ...and the other Sony - WEGA 50" Widescreen Digital-Cable-Ready Rear-Projection LCD HDTV w/HDMI Input - Silver ....Could anyone tell me the differences and what does what? the lcd is for around $2300 and the sxrd is for around $3600. Also they both have pc inputs to hook up a computer to use as a monitor but which one would receive better quality?
