Does anybody know anything about these units? I've read some cool stuff on the tidal controllers, but it it really worth the additional money? These are used and seem to be in excellent shape. Lemme' know what you think.

That is a pretty good deal. I run them in my sps tank now. I will never go back to a regular powerhead.
