Buy anything from McMaster-Carr
I just discovered the magical website of McMaster-Carr. They will sell you nearly anything. Prices are rather high, but everything looks to be really high quality, to the level of commercial / industrial demands. Best part: They have no minimum size order! Perfect for the hobbyist or experimenter. Here’s the huge list of things they sell, check out their very excellent website for pictures and more.
