What should I ask $ for these

[hrdneglcry]

I have what I think is a home made reactor but large its 32" tall and 5" across with a pump.

Also I have a larger Euro Reef or Reef Dynamics Skimmer. Its 24" tall and 9" across. It is missing the vent tubing which could be plumbed from the hardware store rather easily and cheaply. I cannot find the model or if its Euro Reef or Reef Dynamics. Its nice and large.
What should I ask for the reactor?
What about the skimmer without the pipe?

Whatever you can get for it. If you don't have the manuals or all the parts, don't expect a lot.
