I am completely happy with my ADS Tech Instant Music. I was surprised by its small size. It does exactly what I need, which is to digitize audio tapes from church in order to burn them on CD. I've done several week's worth of services. It is extremely simple to use with Garage Band. Just plug it in, launch GB, set the input to the ADS device (usually already done) and start recording. Its ease of use can be summarized by saying "there are no buttons or switches on the Instant Music to fiddle with!"
