These are indeed a good deal. Was tipped off to them on another forum site when inquiring about dado stacks.
Picked up an 8" 42t dado stack (four 6t 1/8" chippers, one 6t 1/16" chipper, I think) and 5-6 shims from 0.020" down to 0.004". They mount and cut like a charm. Some of the sharpest blades I've ever seen.
Also grabbed five (six?) 10" blades. An 80t, a crosscut, miter saw (negative hook) crosscut, two combos, and a rip. Couldn't be happier. The 80t outperforms my Freud Diablo 90t Ultimate at less than one third the price.
Fred's pretty nice too, if you PM "onsrudcutters" I think it is. He listed several items for me as Buy It Now on request.
