Seriously, check out Harbor Freight for tools if there is one near you. Their hand tools are pretty good, fairly cheap and will get you started. Power tools, not so much, but they do work for starters.
As you break or wear out tools, replace them with Craftsman or another quality brand of tool.
Something else to look into is a "homeowners" tool kit. One of those kind of all-in-one boxes that are supposed to cover everything in home repair.
Depending on what you are working on, a set of nutdrivers or a 1/4" drive socket set is nice for hex head screws, a six-in-one is almost mandatory, but eventually you will want properly sized screwdrivers rather than one size fits none, a 10" adjustable wrench is plenty, channel-locks, wire cut/strip/crimp tool, a clamp meter with thermometer, and a good flashlight should get you started.
Hang out here long enough and you will likely be a hardcore tool addict before too long.
