if you are into gaming, many peeps i know in the field of pcs and programming say that crt's are good, as for lcds, well you sacrifice gaming quality for space on your desk.

www.ebay.com
www.techbargains.com
www.pricewatch.com
and always, always, look for the best value and above said dot pitch size a.k.a. resolution.
