What is the lowest acceptable grade for a master gage set? I'm only machining to within .0001", even that's rare, so it seems like grade 3 gage blocks would be acceptable. Is there a reason to shell out more cash for a higher grade? thanks. :)

You may be OK with a Grade 3 for the stated use. The thing you have to watch here is the reported uncertainties for the blocks, as that will drive the uncertainty for anything you use them for.
