I've used Seow, Futato, and a few others - use Futato. His clear layout and well planned progression of concepts is superior to that of Seow. Also, his explanation of basic Hebrew syntactical categories and their usage, along with the simple and well thought out beginner's exercises which are found at the conclusion of every chapter, are to be preferred. I actually found his Grammar to be enjoyable.
