− | If you | + | If you are working from a kit or a published project consider getting extras of the parts. If you use them once you may use them again. Also the authors of these things tend to know and pick what is popular. Always think about; it there are parts that are exceptions that you would never use again. |

+ | ==If you are working with X then Y where Y will help you find the popular parts== | ||
+ | Note that links may or may not be to the best source. Look around, add a link if you find a better one. Do not delete a link, unless product is gone for good. | ||
