A response to earlier, i enjoy hacking my systems but as of right now this tv only does a few systems, nes, snes, n64, and genesis, the systems which i play the most. I have the majority of my other consoles hooked up to another tv that has an enormous entertainment center i built for all my systems, 12 at the moment to be exact on that tv.
As for tv selections from craigslist, yes as previously stated earlier, the standard fd 27" trinitron is pure gold all around. There are 27" xbr tvs out there and would make for a great selection but are really rare and are heavier than the normal fd trinitrons.They are usually to be had for 50 bucks or less, have great picture for old systems, decent sound, plenty of inputs and include svideo, component, composite, and rf/coax, decent size picture tube, and the best part for many, you can move the thing by yourself without shattering your spine. 24" is the smallest for component input if i remember right. If you are going smaller than 24" get a 20" Sony broadcast monitor, they are rare but more common than the other sized broadcast monitors. If you go with a broadcast monitor, you can get rgb input with the right model.
