This ain't yo momma's off-brand LCD HDTV. Hot off the floors of Circuit City is the Philips 23PF5320 23-inch LCD HDTV. It retails for $700, but the handy-dandy $150 instant savings brings this TV down to $550, which is pretty damn good in my opinion.
This HDTV has up to 720p resolution and unfortunately, no HDMI. It is still a relatively cheap LCD HDTV nonetheless, and includes DVI-inputs so it could even be your computer monitor.
