Most WEGAs have component connections, I thought. When set properly and the signals properly generated, this can look essentially arcade perfect. It'll take a little setting up, but the WEGAs are quite nice monitors, actually, and finding a 32" 4:3 set these days is quite difficult.
S-Video can look pretty darned good, but properly generating S-Video signals from a PC is darned near impossible due to poor design of the PC hardware (hint: the S-Video output on your video card will probably look like crap no matter what you do).
