At the risk of sounding sarcastic, jigsaws are used to cut curves. Yes, it
is hard to cut straight with them.

Depending on your use, you will have to either suffer with a jigsaw or use a
circular saw. They are pretty easy to cut straight with.

What, a circular saw cuts straight and not circles? ;-)
Honest, if the OP does not say *what* he want's to cut it's hard to
recomend something to him. But given him posting in a woodworking
group and (as infered from his other posting about plans for a 13 year
old) being rather young i would recoment a ryoba saw. Hand powered
saws make it much harder to cut off fingers that electrically powered
ones... And if you are still young you should use the opportunity to
learn sawing the right way!
