Need a special tool for a project you're working on? I know, it's tempting to buy one, but then you'd have to store it. And will you use that tool again (within the next three years)?
You could rent it, but that can be relatively expensive (depending on the situation). Still, it's probably a better option than buying something you won't use frequently.
Tool libraries are such a wonderful idea. Some libraries have tools available at no cost; others charge a small fee. For a directory of tool libraries across the country, click here. If there's not one in your area, why not start one?
