I guess I'll ask a question back. What is wrong with just using your ground glass for composition? An alternative would be a focusing frame (Ebony makes these), which I think would work. Or a piece of cardboard with an opening and a neck strap to help you hold it at the correct distance. I must admit that I've never tried anything other than my camera's ground glass, but maybe another device would be a good idea. Frankly, the Linhof viewfinder sounds a little awkward and expensive.
