This is one of those rare instances where WM is actually offering a bargain. Couple that with WM warranty and I figure it's the way to go if you're in the market for one of those.

I hate their high pricing on most things, but there are certain things where it's really a good idea to go with the WM house brand. For example I like to buy their house brand of pumps (made by Johnson Pumps) and bilge switches. Pumps and bilge switches seem to have very high failure rates in-general. If your WM pump/switch dies you bring it in, and they just swap it with a new one. Nice.
