well you could always try multiple copies in store. that's what i did and got a super sharp 18-50 2.8 on the second try. It's no big deal to have to test it, especially since you'd be doing it to the canon anyways.
considering the cost savings, if qc is your only concern i think it's a small cost to try multiple copies.
there's also the tamron vc, but i read that it's softer than the non-vc version, and comes in third with the other two.
