Dr. Ghrist is awesome. He is also doing a lot of great work opening up learning materials to his undergrad students.

I recommended that book as a source when I was teaching calculus, and still do :)

It's a very opinionated book, but that's no a bad thing. And, unlike the Stewart doorstop, it's compact, as a text should be.
