I'll second DMI as I've used their services before and find them to be reliable. Yeah you might be able to come across something on ebay, but who knows if it is a good part or not, and who wants to wait for the right part to come along.
I have purchased a new speed log (paddle wheel type) through DMI, had it in 2 days, and it was exactly what I needed.
I'm impressed with DMIs replacement system, and I'll go with it when my 24yr old Datas go bad, but that hasn't happened yet. http://www.dmimarine.com/products/index.html
