While searching for a Stenner pump I found the lowest price at US Water Systems. You can get the Stenner 45MPHP10 for $206.95 shipped. I chose to get the rain hood and the 15 gallon gray tank since we like the "integrated" look. Just letting you know in case anyone else out there is shopping for a similar setup. You have to use a coupon code that's on the front page (JULY10).
