Anyone have a HOB refug they want to sell...cheap?

[Twisted]

Just started considering running a hang on the back refugium now that my tank is pretty stable, I am currently running a HOB filter. I took the filter material out months ago and just started running carbon in them. I do have the CPR backpack skimmer. So kind of looking for a HOB refugium with a built in skimmer, but I want to be as cheap as possible.
Going to the dixon frag swap, so thought I might check with you guys.
