Dramatically spice up my Windows forms?

Very simple question:

I want to use some sort of external component to make my forms look amazing/professional/legit, etc. Are there any that are completely free AND really good, or would I be better off purchasing a component? If the latter, which component should I look into purchasing? I am only (so far) familiar with Krypton Toolkit. Thanks.

See ... http://www.codeproject.com/Articles/...-Windows-Forms ... and http://www.vbforums.com/showthread.p...ight=xcoolform in which I showed how to use it in VB.

Thanks dunfiddlin. You are always a great help.
