Jon,
thanks, I bought the CMPS12 so will file the emails that discuss it
for when I connect it up.

I like the fact that it has an option for TTL serial communication and the tilt-compensation seems to be quite stable.  I wouldn't hesitate to purchase it and I'm going to get one for myself even though I already have the HMC6343.
