Comment on QA = Time and Money. How much should you invest?

Zero QA, or at least zero QA by dedicated QA people.

Developers end up using QA as a crutch. The end up not testing their code completely, and sometimes they don't test it at all. Too many times I've seen code checked in, after going through code review, that just doesn't work. I'm not talking edge cases, it does not function at all.

Get rid of the crutch, and force developers to be responsible for their code. Developers should do all the QA on their code.

If you must have QA, don't waste them on checking if features are I plmented correctly, repeating a job developers should do. Instead, have them actually check quality: have them look at the whole app or site holistically. Have them try to find the bugs that developers won't be able to find.
