Coax

[pithed2]

First off, I'm a noob to this stuff, so go easy on me.

I've read several places here people are adamant about staying away from TV's with coax only inputs.  But I haven't really heard why.  I know for $50 I can get alternative TV's with s-video or composite inputs, but if I already have the old tv, why? 

I'm a visual person, so does anyone have something showing the video difference between s-video and coax with an rf modulator?

RF inputs *always* look like garbage. Don't even bother. Seriously.....don't.

Fair enough.  I'll go with plan b. 

Thanks!
