The skill saw will work that way also.
A fine jigsaw blade will not clog if you put it on slow speed and advance the saw slowly, and IMO
will give you a cleaner cut with less chance of chipping the acrylic. On another note you should put masking or painters tape on both sides of the acrylic where you are going to cut and cut through it just for insurance.
