I can guarantee you that the taps and drill bits you've linked are complete garbage. You simply cannot purchase quality cutting tools in that quantity for that price.

I would recommend buying taps as needed (and high quality ones...we're not talking $10 a piece either, more like $2-3).

If you want to get the all in one drill set, at least buy 5-10 quality individual drills of common sizes (#7, #21, #29, F, etc). Those 4 will probably be your most commonly used drill bits if you use #8-32, #10-32, and 1/4-20 hardware.
