The introductory one is known as Baby Rudin and is a pretty good first exposure to real analysis.

This one? "Principles of Mathematical Analysis"
Yup. You can get the international version for cheap: https://www.amazon.com/Principles-Mathematical-Analysis-Rudi...
The fact that US version of this book from 1976 remains over $100, while the international version is under $10, and the Kindle version is over 50% more than the paperback, is such a perfect example of everything wrong with the textbook market.
