Both available in Home Depot or Lowes near the windows and glass. Usually there is a sectoin on an aisle that has a large glass/plastic sheet cutter, and bins beside it that have various sizes of polycarb and acrylic. I've gotten the 8" x 10" sizes recently (about the size of a window pane) and seem to remember that plexi is around a $1.50 and Lexan is $1.75 in those sizes. They can cut it for you to different sizes too, but you stiil pay for the sheet it came out of. I imagine other hardware stores, craft stores, and even picture framing stores would have something similar.
I use something like plexyglass that is advertised as "syntetic glass". I don't know the composition, but is very clear. It can be saw with a regular saw and drilled with a driller :) It doesn't crack while sawing if you pay just a little attention. Comes for 3.80 € for 25x50 cm. See my robots for more info :)
Polycarbonate is available on ebay like crazy...even Lexan. I bought some nice half inch thick sheets from an ebay store for a vacuum chamber that I built so I could cast parts.
Also if you place a strip of masking tape along your cut line and use a fine tooth carbide blade you will reduce chipping and melting....just go slowly and cut through the tape
In fact, is acrylic an example of a polycarbonate?
Nope. Polycarbonate groups are compounds linked by a carbonate molecule O-C=O-O, acrylic how ever is poly methyl methacrylate (PMMA)...ofcourse there are different various of each, much like metal alloys.
Lexan aka polycarbonate better

On this note
Is Plexiglass acrylic?
Is Lexan polycarbonate?
Yeppers
Uh-huh
Yes, but I'm trying to equate the trade names to the actual material.
