Could someone please tell me if the JV 20-80- is a lot better than the smaller JV 10-80.I do not think I will ever buy all the expansion boards for the 20-80, or is the JV 20-80 such a lot better overall?.Maybe Fran will also be able to help. It is a lot of money to spend and I would like to do the right thing.Thanks for a wonderful and informative forum. If it was not for this forum I would have bought the wrong instrument for my needs. Happy festive season to all the musicians....hein
