Yea, very cheap. I tested a USB soundcard to see if you could use it like that it I was able to. Just think, with a cheap modified soundcard and my free laser show software, combined with a cheap DVD burner laser and galvo set you could be up and running with a 30K 300mw red laser laser scanner for under $400! That's a complete package for less than what most guys are selling just their DACs for.
