UMIK-1 at a good price?

Options
I was thinking of dabbling a bit more into REW this spring. Anyone looking to get rid of a UMIK-1, preferably not the first few batches as I heard there are issues...but those threads on another forum were too long to read through to see if there was an easy fix for the first few batches...looks like later batches corrected the issues. I no rush as I probably won't get to it for a few months.
