- Ponoko sells a range of laserable materials.

- Ikea sells lots of small wooden items (spoons, coat hangers, wood cutting boards, etc) that can be laser etched as great gifts.
Acrylic: Cast and Extruded. Cast has a more uniform size and will produce a better raster effect. Extruded works well for cutting; thickness can vary a bit across the sheet. Cast has a paper protection on both sides that can be removed after lasering. Extruded comes with a PVC plastic protection layer on both sides that needs to be removed before lasering. Commonly comes in 3mm, 6mm, and thicker.
Tap Plastics web site A large selection of acrylic plastic, both cast and extruded. Usually have a bin of remainder odd size pieces for a few bucks each. They also sell a lot of other plastic products that are not laser safe. Ask them before buying something besides acrylic.
