Well. I've been looking at the new version of the Jebo 520 and it looks like it could kick some serious butt.
The new unit is an out-of-the-box rig that has the same 6-inch reaction chamber as the old model and comes with an (alleged) 840 GPH pump and all the required fittings to make it run.
Granted, it's not a needle-wheel design, but, with a pump that strong, I'd bet you could pull some nice gunk.
And the best part is, you could buy a brand new unit for $90 shipped.
I wonder if any of the skimmer gurus on this board (that's right Luke33, I mean you) have seen this model and what their thoughts are.
