k i bought that diamond cutting piece for the dremel, do you guys think i should do my window mod with my cordless dremel or should i just buy a jigsaw?, and my window mod is gonna have a lot of curves.

Try it out, I don't have a cordless dremel, so I don't know how long the charge lasts.
That wheel should cut faster than the abrasive disks.

Either way, if it poops out, you can continue with the jigsaw really.
If it starts dying, use the disk to widen the slot you're cutting, so it will be easier to insert the jigsaw blade. Then carry on from there!
