I think pretty much any generic kit would be satisfactory for most circumstances. An anti-static wrist strap along with a screwdriver with a few flat-head, phillips, torx variations is going to cover you for the most part. A little adjustable mirror and a needle nose pliers or tweezers are great for when you drop a screw. Maybe an RJ-45 crimper and ethernet cable tester if you're making cables. I've had to solder occasionally to repair/replace laptop jacks. I don't think I've used over half the tools in my kit.
