They certainly do multiply, celtic101.
Mine don't all fit in the display case so a modern M400 tortoise, 2 old style M200s and an old M100 live elsewhere.
I don't have the M800 demonstrator version, but that's OK... can't have everything.
The Renaissance Brown and the pre-2005 Black M800 are the current users... the latter just repaired courtesy of Ron Zorn's priceless advice.
I wonder what the next releases are going to be in northern hemisphere autumn.
Stop it already!
