At least the Torx driver sizes are the same for metric and imperial (unlike hex heads where you need a separate set if you need to do anything with imperial screws/bolts). I find three good drivers are enough for 95% of what you need for electronics, and then a cheap interchangeable head set gets you the rest of what you normally need.
