As for epub -> mobi via calibre, I find it more convenient most of the time to just use kindlegen.

Isn't kindlegen, or kindlegen through Previewer, the only "supported" method of conversion? I know calibre can do it to transfer directly to your kindle, but I thought it had to go through kindlegen for submission to Amazon??
