I've always bought tools individually when the need arose and I didn't already have the tool(s) to do the job. Definitely would start with a medium width single edge screwdriver, a full sized phillips head screw driver, a slip joint pliers and/or a full sized vice-grip, long-nose pliers, a cheap set of jeweler's screwdrivers containing a small assortment of both single edge and mini phillips head screwdrivers, a claw hammer or tack hammer, and a push drill with an assortment of drill bits that store in the handle. If storage space is important, a push screwdriver that holds a small assortment of both phillips and single edge blades and can be locked so the tool can be twisted like a traditional screwdriver would substitute for the two separate regular screwdrivers and provide a modest assortment of blade sizes as well. As you're not dealing with any sharps that can cause injury or be damaged by hitting other hard objects, I'd put them all into a moderate sized hard plastic refrigerator storage box with a snap fit top. You can even line the inside of the box with a dust rag or old dish towel to minimize rattles. Buy the tools first at a big box store if one is convenient and have them all with you when shopping for the box to ensure an appropriate size.
