Any mid-range point and shoot will do the trick especially for rough handling (shop work). Look for good macro and ergonomics. Review white balance errors. Some cameras tend to be a different color on-screen than in the computer.

If he ask me personally I'd say get a (insert brand) DSLR but that might be too much for what's needed

If waterproofing is needed, Panasonics are good. I borrowed a friend's 12MP Panasonic Lumix w/ Leica lens - waterproof and great photos.
