Makes sense. With the jigsaw, you get what you pay for - I bought a £18 own brand jigsaw from B&Q last weekend and the blade doesn't quite line up with the guide on the base plate so I've had to mark where it is on the plate so I can cut relatively straight. My jigsaw has the same power output so yeah, should be OK with a wood cutting blade, which you can also use with HDPE as well.
