I applaud Peter for his efforts to fill a void in the blade offerings for the Festools TS saws. An inexpensive blade has great utility. E.g. laminate flooring dulls even top of the line carbide blades amazingly quick. That super duper 20 year finish is attainable because of the aluminum oxide coating, similar abrasive to that used in sandpaper. Senseless to use a $50 blade for that purpose. I would eagerly purchase a few $10 "disposable" blades if available.
To opine that an expensive saw shouldn't use inexpensive blades is preposterous. I have a Unisaw and have a cheap Crafstman blade I swap with my Forrest WWII for use with pressure treated lumber, recycled wood, cdx ply, etc. No need to dull or damage the WWII for such mundane tasks. The ability to use an inexpensive blade is not an affront to the tool.
