I have the VS840 with the VS840EX "system upgrade." It's a great device. (The only thing that sucks about the unit is that Zip discs have not gone down in price in over 8 years!!!!) I have the manuals for the VS840 and the VS840EX. If you need help on a specific topic, I would be happy to help you out through here,email,mail or phone. Recording is a breeze with the 840. Editing,however,is tedious. Copying/moving sections is difficult to get perfect. It's not that easy to copy and paste without a monitor! It can be done though. I have recorded some great sounding stuff with the 840. Let me know what you need help or advice with.
