My professional preference is PH Tool, reachable at phtool.com. I have scrapped 2 IIW Type 1 blocks in the past 5 years. They were made by minor shops, and were so inaccurate they skewed my calibrations. All PH Tool blocks I have used are very accurate and well made.

My personal preference is the same -- Phil Herman is a good man to do business with.
