I have a DSE system for sale. Includes the barrel, hoses, filters, and drill pump. Also, a few bottles of DSE ingredients are included.  I bought unit in April 08, with big ideas. unfortunately, I am not up to this due to time constraints. I have about $750 invested. I am willing to sell for $600. Help me out, my wife is pissed.  Rick

It would help if you included breakdown of the specific part numbers, manufacturers, and costs.  I doubt anyone here will be interested in the DSE, but some may be interested in your parts.
