Cutting a strait line with a jigsaw, is a stupid waste if time, there are faster more efficient ways...Bosch for example makes a really nice jigsaw, (7 amp, although @ 160.00 more than a cheap tablesaw) it will cut steel like a beast and has quick release blade change, and a light. But try cutting a long strait line on a midway cab, or a long sloping curve with any amount of accuracy, ya not so much, It chatters, wanders, drifts, blade flexes, and for what? A template with one good side only if you go really slow and try really hard to be absolutely perfect?
