Another one to consider is the Johnson variable rate. I hadn't noticed them before, so they may be fairly new on the market. I have tried the above pumps, and also a Marco, and none of them worked properly for me. I got one of the Johnsons this spring, and it has worked flawlessly. The other ones, for some reason, would let air get into the system, and then they would just run without pumping anything. Very pleased with the Johnson so far.
