Funny you should mention plywood; I've gotten good results using a plywood
type blade in a table saw on 1/8th inch acrylic.  The idea is to get a large
number of teeth per inch.  With a good guide/fence on the table saw, nice
straight guts and right angles are easy to do.

If you're using the standard "glue" for the stuff, which is really a solvent
that "welds" the two surfaces together in a few seconds, good cuts are
important.  This joining process is very poor at filling gaps, but produces
good results.

I think that the reason power toos cause trouble is that the acrylic is
a rather poor conductor of heat, so if the blade heats up, the heat has
nowhere to go (unlike cutting metal, for instance).  If the workpiece melts,
things get rather difficult - it may weld back together after the saw
blade passes by!  Use care when drilling also; similar problems can occur.
I haven't quite perfected the art of drilling the stuff myself.
