Hello Rick,
I have read somewhere that you might increase battery life of the 675 cells slightly if you glue shut one or two of the "air holes" of the battery. As far as I understand, the more expensive Wein cells do actually have fewer holes than 675s and therefore last longer, but differ only slightly in voltage (maybe because of the decreased air intake?).
Since I have not tested this myself, I can not guarantee it will work, if you take a lot of pictures, this might not even be an issue for you.
Otherwise there is another alternative to the C.R.I.S. MR-9 adapter. There is an in-depth analysis of the whole mercury cell problem by a guy named F. de Gruijter that also explains how to make an adapter by yourself. So if you are handy and have the necessary equipment, you might produce a fine adapter to work with the silver-oxide batteries for something like $ 5. The guy also sells adapters for € 15 including shipping, so this seems like a good option as well.
I will probably get one of his adapters soon (as soon as I have checked whether my camera even still works properly), so I might report on it later.
