Hiya Mike-I hand these addresses out a lot 'cause I & various pals have had good luck with them. roguemusic.com in NY has an on-line list of used stuff, including sound cards & disks. Its a random, catch-as-catch-can deal, of course, but the gains are real enough when you hit the mark. Likewise, try kidnepro.com for retail sound banks, korg.com (obviously), ugbm.com (Used Gear By Mail) and wurlitzer.com. Also check out keyboardmag.com, if you don't already read their magazine. Its the keyboard source to end all. Good luck!
