I will try to post the link to the tach that I have, nice thing it can be used to measure the speed of anything. I am not sure this is the supplier that I bought from but the one I bid on I think I got for lessthan $10.00 with free shipping, I have used it to check the speed of several of my tools and it works very well. I don't think anything else I have seen can beat the price. The mactach is committed to a single machine at one time, this is very versatile. tom
