I looked at that very one and am seriously considering it. Thanks!I would recommend Octopus or Tunze. I like the INT skimmers by Octopus. The Tunze skimmers are highly undervalued, and the service from Roger is legendary. I once had him get me a replacement pump for a 15 year old skimmer. I would consider the 9430. It is at the top of your budget, but having used it I can tell you it is one nice skimmer.
