Brett (or anyone),

Can you describe the similarities and differences between:

	M52	S52US	S52(Euro)

The differences are often alluded to in this digest; people are often
discussing overcoming them; but I've never seen them explicitly enumerated.
Which parts are common?  Which parts are interchangable?  Which are fundamentally
different (better/worse)?

Thanks in advance,

Brian
