We just completed our first duplication job with MST Productions of San Ramon, California. I learned of them from a posting here on the COW about copy protection and was impressed that they could do relatively small numbers of copies for a relatively low cost. Other copy protection that we had looked at began with much bigger numbers than our job would entail.
We are very happy with the quality of the work, the quick turn around time and especially impressed by the responsive service provided by owner Matt Townley. I highly recommend MST Productions for duplication.
