That's oil and water right there. Do you want the best picture, or do you not want to spend a lot of money? You have to pick one, you can't do both.
If you truly want the best picture quality, save your money for an XRGB Framemeister. Let me tell you, I didn't wanna spend that much money on one. So over the years I bought all these different cables, adapters, converters, scalers, etc, only to never be satisfied with any of them. In total, I spend almost as much as the XRGB costs! I finally got an XRGB, and after using it, I wish some one told me exactly this. I wish I saved my money and got one from the start instead of buying all that other shit.
If you don't actually need the BEST, but you just need something that allows you to use your HDTV and not look like total shit, then there's plenty of things in the $50 range. I was using
this for a while, and it really wasn't terrible. There's also SCART-to-HDMI versions of that same chipset. I was using it with S-Video from my SNES and N64 and it wasn't bad. Not amazing, but not bad. It got the job done.
If you decide to do something with component, like Claw said, be sure that your HDTV can accept 240 over component. Easiest way to do this, if you have the stuff, is to play a PS1 game on a PS2 over component.
