I’ve got one that I have had for years on my computer. Can’t tell you where it came from, but it still seems to work reasonably well as an estimator. Jim just refers people to the web. There are several that other companies use. One thing all of them seem to fall a little short on is balance point. None of the ones we have seen take that into consideration. We should develop one. If anyone should have one, we should, but it would take some time. Might put it on the to do list.
