<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> <body bgcolor="#FFFFFF"> David, The first thing is to be sure that the problem is caused by high humidity.  A client will not be happy if you install the components and the problem remains.  Since I live in an area where we go through a wide range of humidity annually, I ask if the problem goes away during the dry season.  If it doesn't, controlling high humidity won't help anything.  But I've never been to California, so I don't know if that's a practical suggestion for you. I don't know if prices from distributors are identical, but they should be close enough to each other that I wouldn't make that an issue.  Take your pick.  For reliable installation information, contact Dampp-Chaser directly (telephone 800-438-1524), and they will be happy to help you. For the piano such as you describe, I would use a 48-50A dehumidifier and an H-2 humidistat.  Mounting the rod about halfway between the keybed and the bottom, or a little higher, should work just fine.
