OK so I hear a bit about soundfonts. I guess they are supposed to be better in sound than a VST. Also more expensive it sounds.

What do I need to try soundfonts. It seems to me I heard there are some good free soundfounds on the internet. Where might I find those and what might the good ones be.

I use a studio quality Mia 24/96 sound card. What do I need to put these soundfonts in? Do I need an Audigy soundcard, or is there something else, hopefully free, that will work with my sound card?

Thanks for the help from someone who hasn't a clue how this all works yet.
