I agree. I also bought word2tex after trying all the free options. The problem with OpenOffice, at least when I tried it, was that it tried to copy the exact style of equations into latex, so the resulting latex was a terrible mess. Word2tex has worked quite well to me. It is not completely automatic. I usually do some hand editing of the latex code before finally converting it into LyX.
