ReefFlo will spank the others. Second, I would go Deltec 902. The 902 is a well made skimmer, but still, its no ReefFlo. The ReefFlo will compete with the likes of the Bubbleking deluxe 400-500 series. Bang for the buck, its hard to beat, because the body is made by Octopus/Shenzhen-Honya. Its a solid design though that will outdo most anything else on the market though.
