(Takes some work, though, but I've managed to buy some 80 lbs. of books from them. So far.)
There is a translation of the "inner chapters" by the philosopher Feng Yulan, from 1933, that I haven't found yet, but it might be interesting. The rightly famous writer and lexicologist Lin Yutang published some excerpts in 1948, The Wisdom of Laotse.
