Thanks for digging out the links for me.

The LC-1 still seems to offer alot more than I want and I'm loathe to pay for something (albeit a very smart bit of kit) if i'm barely going to scratch the surafce of it's capabilties i.e. end up paying for stuff i won't use...

Can you see where I'm coming from?

There must be simpler (cheaper hopefully!) system for monitering lambda... maybe...?

Many many thanks again for helping me on what seems to be a deeply unpopular subject.
