I saw several what looked like home made versions of these 
at OSH for $1000! I was in Harbor Freight and saw this one for $125!
Whipped out my check book and bought it on the spot.

Will cut 1/2 aluminum plate slowly so good for making intake
manifold flanges and other parts that need complex shaped holes
with tight radii that can not be done with a band saw.
The throat depth is 22 inches. The universal motor claim's
to be about 3 HP. The blade is a stock 5 inch jig saw blade.
