RE: tool for starting/holding tiny screw heads?
I'll second what GalenB says, you will never regret getting a good set of JIS screwdrivers as most of the small electonics gadgets we use all use JIS type screws. They may look like Philllips heads but they are much different. Once you see the difference in how well they hold a screw and how much torque you can use without stripping out the heads, you will be glad you made the purchase. Most hobby shops carry them.
