The pump I have is made by Alloy Marine Inc. called the Suck Up. In a quick look on the net, everyone is really proud of these now, the cheapest being $62 and up to the mid $80's. It works great, but I wouldn't have bought it for that much! The Topsider made from a steel 2.5 gallon can works good, and Overtons has them on sale now for $33 and some change. This is a real good unit, the only reason I bought the other one at the time was the prices were reverse of what they sell for now!
By the way, in looking up the Alloy Marine Inc. website, they make some really nice quick disconnect and folding swim platform brackets that I know I have seen someone looking for on here. They don't list a contact number or info, someone with killer net skills will have to figure that out.
