Low quality hex wrenches that round out hex bolts can be really expensive. If you cant buy separate high quality hex wrenches buy the whole set, and only carry the ones with you that your bike needs.

BTW there is an old saying that I quite often use. If the old farmer want high quality hay, he is going to have to be willing to pay for it. If he doesnt mind hay that has been thru the horse once, of course he can pay less.
