I bought a sheet of 48x24" plexiglass at home depot (maybe about 1/8"
thick).

I am trying to cut in 7" slices (each 48" long).
Per the instructions from the Home Depot guy, I bought a blade that is
supposed to score the Plexiglass and then you snap it.

Well, I am having 2 problems.
First, I am finding it hard to score precisely on a straight line
(even though I am following a steel straight edge). The blade keeps
wanting to slip away slightly.

Second, after scoring with several passes, when I snap it, it ends up
breaking only partially along the line (and the rest breaks away at a
short angle).

One solution, would be to just be more careful on scoring the line and
then scoring even deeper with more multiple passes.

Are there any EASIER and MORE accurate ways to cut plexiglass?
Can I use a regular table saw blade (or will it shatter it)?
What about a jigsaw or a dremel?

Thanks

Thanks for all the MANY helpful responses.
At the suggestion of one user, I ended up taking the easy way
out. Instead of going back to Home Depot, I went to Lowes where they
not only sell but also cut plexiglass. They had a nice panel-cutter
type machine but even so the guy ended up breaking a sheet before
taking the time to score it enough to make clean cuts. The good thing
is that this time the breakage was on him. And also, he didn't even
charge me for the 4 cuts required!!!
