Trying to find a 13" or 15" CRT to use for my NES/SNES/PS1 systems. Any recommendations?

Maybe a Sony 13FS100 seeAmazon, (http://www.amazon.com/Sony-KV-13FS100-13-Inch-Trinitron-WEGA/dp/B00006JP8U)where you can look at the manual. Might be able to find on Craigslist or Ebay. It has 1 front Composite, 1 rear Composite/Svideo, 1 Component video.

Does it need to be an actual "TV," or will a monitor do? For monitors, you can't do much better than a Sony PVM-1354 or PVM-14M4U. These are excellent broadcast studio monitors that give an excellent picture and go for around $150 on Ebay in great condition.
