Replacement of Sony DSC-S75 mode dial.

I have an older Sony DSC-S75 digital camera that needs a new mode dial. I took it to Hong Kong a few years back and most of the decals have disappeared because of the humidity. Is there any inexpensive way of replacing it? Most camera repair places want $150 and I don't feel that it is worth it.Popping the dial off and replacing it with a new one seems like it would be fairly easy. Is there a place other than Sony to purchase this part?
