Hi Dave,
This is the only model
LM-1 there is, but I assume you're wondering if it's the new LM-2.
The LM-2 has not been released yet and it looks like sometime in June for the release date.
This price is for the trusted and tested
LM-1 which has been out in the field for several years. It's about to be replaced by the LM-2 which has new additional functionality, but is more expensive and "new" (untested in the real world at this point).
We'll have the LM-2's just as soon as they're available but at this point, we haven't been able to get even a test unit over to our developers who are working on a new software package.
