Hey guys I am converting my cassettes to mp3's and I am using the sound input on an old blueberry iMac dv. I have a new imac but it does not have a sound input. I was wondering if there was a usb or better yet firewire conncector that would allow me to record my cassettes at a high speed and what software could I use to do this. I would like to stay around $100 -$200. Thanks for all your help.
