English Grammar in Use

I have a spare time from the coming few month.  Today I go to The Commercial Press (Book Centre) buy a grammar textbook for self-study.  I find that English Grammar in Use 3/e ($173.00) is quite good and easy for self-study.  There have a same grammar textbook with translation  and the selling price is cheaper than the original one.  I compare with these textbook and read a few chapter.  Lastly I am choosing the original one without any translation.  I think this is better for my self-study.
