[Steve Katz] I use a Craftsman Roto-Zip type saw (rotary blade,
hand held tool, costs $49.95 with a million accessories), it zips right
through plexiglass like butter and can cut a very straight line (or any
other shape) if you want it to, by simply guiding it along a straight edge.
I bought it to cut ceramic tile, which it also does quite well, especially
for $49.95... -WB2WIK/6
