Hi DB
I can't suggest a particular jigsaw to buy but I'd like to draw your attention to the problems I've had with a Bosch. It has a peculiar blade fitting system that involves you lifting a catch, rotating it counter clock-wise three times, inserting the blade at 90 degrees, closing the latch, twisting the blade through a further 90 degrees, rotating the catch twice clok-wise, sacrificing a goat at dawn and dancing naked widdershins around a rowan tree. Or something like that.
Then you try to use the saw and find the blade wanders off course before disconsolately dropping out of the machine.
So, to summarise, before you buy, it's probably a good idea to make sure you check out the blade changing system.
Yours
Gill
