I am in the market for a 27-30" TV. Brother offered his regular 27" sharp for a VERY good price. Before he brought that up i had my mind set on a flat screen. I am just a college student, I'm not ready to drop an assload of cash on HDTV and all that. My question: Is an 'off brand' flat screen 27-30" TV worth an extra 100$ more than a regular TV of the same size?
