The last specialty bits I bought in a bind at Sears, 50$ or so and felt robbed. Some of these new things probably are improved. The one place I make some investment in is small drill bits from a USA vendor at the flea mkt. About a dollar or 1.25 a piece for a 9/64 or 5/32, just right for pilot holes with battery drill,,, along with enough skill to hit the spot. I did one the other day with a drill for giggles, once I got started I could see I had it perfect, punched right thru the center of a 3/8 bolt, got it so good I drilled it 5/16 and it came right out, it dont always happen, normally first resort is to weld it out.
