I bought a 20 inch model scrollmaster as a back up saw a few years ago. If you look closely at the tag it says Made in Taiwan. It appears that they had no blower system as mine came with a aquarium pump. Drawbacks are all tensioning is done by knob in the back, tooled blade change, and single speed. Parts look like they will exchange with a single speed Hawk, but I never tried. I paid $60 for mine in like new condition.
