Note: Many of these companies make products that fit under various headings. I'm going to try to put links to specific products under the appropriate headings (or else just repeatedly put the main link under different headings), but in some cases I'll just put one link under whichever heading I feel is most representative of the type of products the company makes, so please don't assume that any of these links might not have other types of products, despite their heading. But I'll also have a "miscellaneous" heading for anything I don't feel like putting under any specific heading. I apologize for any confusion...
