Online seller of reletively inexpensive float switches and other related parts for the DIYer. Shipping was fast, and his communication via email was almost instant when I had questions/comments. Ordered a few switches from him and they work fine. Has plans on his site to build a simple top off setup, but haven't try it. I know there was a group buy at one time, but fell thru I think as he only accepts Paypal. Free shipping if there is over $100 for the order.
