I've had a VGA to Video transcoder for quite a while and they work quite well for playing video. S-Video cables can be run much longer than composite.
They are not going to make computer text very viewable, however, so using a TV as a PC monitor will not work well. If that's the goal, then you also need to drop desktop resolutions and change fonts and dialog box sizes.
If you want to use a TV as a PC monitor, then your best bet is to use an HD or HD-Ready set with Component cable at HD resolutions. You're not going to get S-Video or Composite to display text well.
An RF modulator will never display text well since it's horizontal resolution is generally 230 lines. It's bandwidth limit is under 3Mhz but broadcast video has about a 4.5 Mhz range. For text, S-Video is almost acceptable, but not Composite or RF channels.
