Take a look at "A Book of Abstract Algebra" by Charles Pinter. It's published by Dover, so very affordable. I've seen it criticized as too verbose, but that worked for me.

It has been my experience that complaints about a source being "too verbose" rarely come from people learning the subject.

Thanks! Verbose is fine, the more explanatory the better.
