I use regular hole saw to drill acrylic.  Start drilling from one side apply very little pressure (if not you can catch the saw and crack the acrylic).  When you are about 1/2 through the acrylic drill the rest from the other side (you should have a pilot hole so your holes should match up exactly in the center).

Exactly. That way you don't get chips on the acrylic. If it's 3/8" or thicker you may also consider keeping it wet while you drill it, otherwise it can start to melt from the heat of the hole saw.

Steve,
 
I had thought I had mentioned the melting thing, but I didn't.  It is a very good point.  I usually don't use water, but you can.  If the acrylic starts to melt then I usually stop and wait until it cools down.  Usually if you have a sharp hole saw and don't push too hard it won't melt.
