A quality set of slotted and cross point screw drivers will cost more than your camera. However they are well worth the cost if you are going to be using them to dissemble cameras and other precision equipment. Anyone who has ever buggered the head of a screw by using the wrong size screwdriver can well attest to the fact that quality tools are cheep at twice the price. The cross point are the hard ones to come by most of the cheep sets are way to large for use on camera equipment. Micro-tools XPT-SET-2 are excellent and the Starrett Jewelers screwdrivers are as good as they get . They will cost you about $80 for the two sets. You may want to look into a set of spanner wrenches also.
