So, I seek recommendations for legacy audio input hardware for plugging in a guitar & mike based on real-user G5 experience with GarageBand. Then I'd make a note for searching eBay at a later date. There was an interesting legacy firewire PreSonus product I remember reading about. For some reason, I think Firewire is preferable to USB 2, but that may be a non-factor. This is for a simple set-up that my nephew could gradually expand on. Right now the set-up has GarageBand from iLife 09. Thanks for any input.
