You want to give the handyman/woman thing a shot, but you don't want to invest in an entire toolbox worth of gear in case it turns out you're inept. Try Black & Decker's new Modular Matrix system -- it fits most of a workshop in one relatively affordable handheld tool.
Other modular tool systems let you share a rechargeable battery between multiple devices, but the Matrix base power unit lets you swap in different heads for different jobs. The single handle comes with a drill/driver attachment, which pops off for use as a sander, impact driver, oscillating multi-tool, jigsaw, router, or a trim saw. The rechargeable base units come in a 12V model for $US50, and a 20V model for $US70.
If you don't mind a cord, a 4.0-amp AC tethered model will set you back just $US40. And the six attachments will range in price from $US30 to $US40 when the whole system goes on sale in January of next year. Wannabe carpenters of the world, get your lumber ready.
