I have been looking at skimmer options for my 300g+240g setup and they are ~$800+. I thought about looking into DIY skimmer and found a few post on here and other sites on how to build one. However, I see all these plans but no one ever really confirming if it was worth doing or if they should have payed for a brand name skimmer.

What do you think? Are there some good plans out there that are confirmed working? It does not seem to complicated to do.
