I've actually had great success with the Aura ones. Granted I used them to enhance the experience not as a significant supplement to the LFE experience. In fact, I have 6 of them still in boxes waiting for V4.0 of my theater. :-)

A lot of bang for the buck, but you are right, not the same level (or cost) as the other options.
