I do have a Reef Octopus BH1000 HoB skimmer, but after I bought it and used it for a few weeks I decided to just upgrade the whole tank so I'd be willing to trade that. If you aren't interested in that trade.
If it will fit, a skimmer is never too powerful. You can make any skimmer skim more dry if it's pulling out too much crud. Overdoing the skimmer can allow you to increase your stocking to a territory limit rather than a bioload limitation and if you ever upgrade your tank, you won't need to upgrade your skimmer.
