I'm trying to help a friend set up his Mac for recording but I don't really understand how to best set it up hardware wise. He got a new iMac last year and is running osX with garage band. http://www.musiciansfriend.com/srs7...6615946/g=home/search/detail/base_pid/701368/ This looks to be the best option I've found so far. He is telling me the iMac doesn't have a line-in though so will this work? He's looking to spend $150-200 so any other reccomendations would be greatly appreciated.
