I wouldn't buy a toolkit, either. I've had several of them over the years (all of them free, through various means) and have never been satisfied with the quality of the tools in the kit. One of them was a $200 kit with all kinds of goodies, but the tools were junk.
Go to a hardware store and hand pick your tools and a small tool box. I'd recommend a nice precision screwdriver set, an all in one torx driver that has t4-t12 tips, a nice philips #2 driver. Tweezers can be nice sometimes, small needle nose pliers are nice...there are probably other things you'd want but I think those are the essentials
