Thanks for updating your profile. Indiana, eh? You're in luck. Several experienced laserists are close to you. (Close being within a few hours by car.) With luck, you might be able to get together with some of them over a weekend and talk shop. (This would be an ideal learning experience for you, and would also be one hell of a fun way to spend a weekend.)
The Audiolase package includes a sound card and the Audiolase correction amp. So if you buy the complete package, you'll get everything you need. Send a PM to 300Evil (Adam Bourassa) and he'll give you all the info you need.
