"Can't render recorded solos with the on board sound. Any internal or external sound device that will allow rendering of solo pieces to make a cd is what I'm looking for. "

Not sure you need to spend anything. What on-board soundcard do you have? You should be able to render. Soundcard doesn't get involved - drivers perhaps, but rendering something that is already in the computer is not a sound-card specific task.

Are you getting error messages of some type when you try to render at present?

What is driving you to think you need a different soundcard?
