Bad news: I ran out of CEM3310s. Unless I can find more, that's it! I originally bought 572 from Ensoniq 8 years ago. I wish I had 500 more! Good news: I found some very rare parts, just a few. Check the website for details. PLEASE email me first before PayPaling on the <5 piece items. www.synthtech.com click on the CEM tag at the top. Paul S.
