Tiger Direct (www.tigerdirect.com) has some nice Trinitron technology 21" refurbs for $399. I got 2 NCR branded, made my Mistubishi 22" monitors for $399 each and they are very amazing and have a perfect picture. They go up to 2048 by 1536 (3.3 megapixel) with a refresh rate of 85Hz and 32 bit color. They are the seconf best monitors I have ever seen...the best being a 23" lcd at CES (Consumer Electronics Show) and that cost quite a few grand. Good luck.
