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.

San Jose and other locations  Carries a full line of wood sheet goods, including Baltic Birch plywood, as well as an extensive selection of domestic and exotic hardwoods. If you take your Maker Nexus badge, and let them know that you are a member of MN, you will be able to use our pricing level. They also deliver orders over $350, so larger orders can potentially be delivered directly to MN. Coordinate with staff in advance to use this option or delivery will be refused.
San Carlos  has a large selection of great woods. Some plywood panels, pre-cut.
Precut 24x18 panels of several plywoods. Many have a nice finish on at least one side. If you want cheap stuff, look for "door skins" - thin plywood sanded on one side.

Misumi These folks specialize in parts that can be configured at the time of order. I found them referred to from some web sites as a low cost source of accurately cut aluminum frame parts - 2020, 2040, 4080, 2525, etc - just about any size member that is made. You can order cut to length, but also with holes at locations you define and stuff like that. You can also buy stuff like a plate with four holes. You specify all the specs of size of plate, location of holes, size of holes, etc. It's like they've made a bunch of parametric designs and provided a web-interface that lets your specify the parameters and them to set a cost. Cool, cool, cool. These guys are also the referenced "best quality" linear guide rails. But pricing is about 5X a part you can buy from China.
A specification for "all possible bearings" is the NTN Bearing Corporation catalog available on our member share drive.
This Amazon seller has a lot of smaller bearings. There are also Amazon sellers with multiple regular bearing sizes.
Amazon seller with a drop down for lots of sizes.
