Always use the site kAi posted. It is the most frequently updated HxH manga site there is. As for the "bad drawings", atleast Togashi's work is redrawn for the volume (book) releases. Unfortunately nexGear only started doing their translations in the midst of the volume 19 chapters, so the only v2 you'll be seeing (from them) is vol19+.

Fortunately... I have the vol18 raw, so it's just a matter of time before I take a pause from subbing to do some photoshop work...
