I\'ve recently got a G5 and I was disappointed to see that the Echo Gina24 would no longer work in it\'s redesigned PCI slots. Can anybody recommend a card or firewire/USB device that\'s CHEAP and able to do 24-bit recording and work with the Mac G5? Internal is perferred, however. Is there anything under $250? I\'d like the card to be able to do multiple balanced inputs (if possible), but if not, RCA inputs are fine. Also, optical or coaxial S/PDIF output and/or input is a MUST!
