Flat Screen TV

We purchased a flat screen TV at Costco yesterday. I'm not sure I did enough research before buying, but I think it will be fine. It's a little confusing between DLP, Plasma and LCD and then the resolutions and black levels. The set comes with almost no cables, so you have to spend more money on an HDMI cable, but I'm not paying $150 for one. I'll buy mine online for $15. Maybe we can set it up today and see how it looks.
