Context: I am an assistant professor at a small college in the US.
Next semester I am teaching real analysis for the first time, and we are using Steven R. Lay's book. (It also happens to be the same text that I used at my undergraduate institution.) I like to write my own homework assignments, and I sometimes draw on other texts for inspiration.
That brings me to my question: What are affordable and level-appropriate texts that I could use to supplement Lay's book? I have my analysis texts from graduate school, but I am aiming for something softer than Baby Rudin.
