Have you checked out the JBJ type. Plug in your power head, plug the sensors hook up some tubing and set a 5 gallon bucket. Mine keeps it just right. Not sure what a RO line type is.
I bought my controller for about $75 and a used power head for $5. $3 for a new bucket and $5 in hose. I'll ask my friend if he has an extra controller laying around.
