The only issue I had with my PM-25MV was that I had to add 0.004" of shim stock into the bottom front of the column to get the y-axis to tram correctly and the Z-axis square to the table- its not perfect still, but a thou over the travel of the y-axis is good enough for my needs right now. The bolts holding the head weren't super tight, but I had to loosen them for tramming anyway. Other than that, its just cosmetic stuff, but I didn't buy it for the looks..
