I would go with the independent dealer. I just don't like Stenner pumps and had to many problems with Pulsafers. With the Stenner you have to change the tube yearly and I had 3 Pulsafeeder motor go out within a year. It took them a month to determine it was under warranty. In the mean time my customers suffered. I think LMI makes the best pump. There only downside is it does not self prime so you have to make sure you don't run out of solution.
