best tool for cutting insulated plasterboard

[drives]

Hi all,

I've got a load of insulated plasterboard (total 27mm thick- 90mm plasterboard) to cut to size. I've got a cheap stanley jab saw but happy to invest a bit more money to make the job easier/neater. I was looking at something like this potentially:

Any other recommendations?

Thanks

I use my jigsaw - long blade and slow speed.

Hand saw is quick enough!

Thanks..I did try and cut celotex sheets with a jigsaw and special blade and to be honest I found it easier and quicker to use a saw so I’m inclined to stick with hand tools.
