Sylvia is gorgeous! I've been looking at a 6300, but would take a 6600 if the opportunity arose. I love the 9" harp....and the other features that my MC4000 doesn't have. My 4000 was a demonstrator used in a shop and has been in my possession for almost 20 years. It's been great to me. The retired owner of the shop still maintains it for me. Even if you've got to pay a little more, it's good to have someone that you know will give you good service. Congratulations!!
