I'm curious why there never seems to be any mention of the NEAT pads. I've been very happy with them and I use them regularly along with Siaair pads. Very long life pads, so the cost is reasonable to me. Not a fan of the lower grit Jost pads as they just don't seem to hold up, and I haven't tried their 4000 pad yet, but will now based on Charlest's comments.
