Here is the link of the auction for a Sequence 1000 series pump that is being offered by the guy that I bought mine from. The have cosmetic ware but these pumps go for around 600$ and they can be rebuilt. This one puts out a 23 ft head - it is a monster. I bought the first one he had for 116$ that included shipping. http://cgi.ebay.com/KOI-Pond-Sequnce-Wa ... dZViewItem
