What soundfonts would you recommend?

I am having trouble finding a quality soundfont. The soundfonts I have used were free, so I guess you can't expect much. I'd like to know what soundfont you use, or fonts that you recommend.

Also, I don't think my pedal is properly linking up with the app. It's very noticeable when I play Chopin's Raindrop Prelude. I'm not sure if it's because of the soundfont though.

Thanks
