In the classifieds section, you can find any kind of used instrument available for auction, be it a hand tool or a power tool.
However, it is always better to ensure that you have purchased your money's worth.
Usually, the price of any used item is nearly half of the new one.
Use a Craigslist search tool to investigate the original price and compare it with the item put up on sale.
If the price is approximately same as the actual cost, then chances are that the tool hasn't been used much.
This way, the tool quality would be assuredly better than other cheaper ones.
However, this rule need not apply equally to all the tools and discretion must be used.
Every seller praises his item and says that it is 100% in working condition.
But, if the price tag reads a cheap value, chances are high that quality is also cheap enough to end up in the trash can barely a month later.
To avoid this scenario, it is prudent to weigh both the quality and the price of an item by perusing the reviews and ratings left by other customers.
Reviews are also helpful in isolating old tools from new ones.
Old, rusty tools and electrical items must be thoroughly checked by testing the noise they make and their charge holding capacity before purchasing.
A classifieds search tool can be used to your advantage by searching the tool type and the brand name.
This often produces desired results as a good brand name like Craftsman or Black and Decker ensures the expected tool quality.
