   My $25 Swiss ones are 304 stainless.  Look for "antimagnetic"   
   laser-etched on the side.  You can also get titanium ones.  One useful   
   tip is to take a miniature binder clip and slide it up and down on the   
   back end of the arms to make adjustable self-closing tweezers.  That way   
   you don't lose stuff when you change your grip.   
      
   The $5 Aven antimagnetic stainless ones from Digikey are also OK.   
      
   Cheers
