Yes, it would have been cheaper and faster to throw this code away and start over
Maybe. For another point of view, see Joel Spolsky on not rewriting from scratch.

I agree with adrianh. If a component is not broken, don't rewrite it. Rewrite a component when you find a number of bugs in it. But first write a regression test suite for the component. I've seen many folks over the years throw out old code, rewrite it ... and introduce a heap of new bugs in the process. If you come into a new company and introduce a swag of new bugs in previously working code, you will start to smell very badly.
