You can DIY a simple household toolkit for under $100, which we certainly recommend, but this requires omitting one item that many consider essential: a cordless drill/driver. A quality drill with a battery will usually cost between $100 and $150, demolishing a budget. But if you're planning to work with heavy-duty materials, an electric screwdriver can give you the same convenience at a much more affordable price. The average cost for one of these tools is around $50, and in many cases, they don't require you to purchase a separate battery or bits. But even if you shell out for a more expensive brand, you shouldn't expect major pain in your pocket.
