Grammar Book recommendations?

[emmaMBC]

I'm looking for a really good, covers everything grammar book to keep as a reference when teaching, and to gem up on the finer points for myself.

Anyone have any recommendations.

This is excellent.

This one's pretty good for the basics, unless you are into further linguistics and grammatical obscurities.
