Did you see my Coherent C315m that I borought to the meeting, it was shining away merrily on the back shelf! That is a beautiful example of a single mode holography laser and there's a reason they are so expensive - stability comes at a price!
You could always set up a basic interferometer to test the stability of the CNI units, but I think it would probably be safer just to say they're not suitable.

P.S. Before anyone picks me up and says the C315m is not strictly single mode - Yes, I know that there is another line a few nm away, but its presence is not relevant.
