Keep an eye out in the selling forums and on the local site for people getting rid of theirs. Gotta be quick on the draw but you'll find a good deal. I think I got my Coralife Super Skimmer 125g for $120 shipped new.
People are always upgrading, getting out of hobby, etc...
I personally couldn't comment on the Jebo but I simply followed everyones advice.
They said, "DON'T BUY A CHEAP SKIMMER"
You can also post something in the Want To Buy section.
