Can you give me an idea on how much this stuff is worth

[yetex]

How much would you pay for a used one?
And how much for a CPR SR 4 skimmer with pump rated for 125 G - used
CPR CS90 overflow- used?
Mag 5- used ?
Berlin Classic protein skimmer - used?
Im in the market for used items and dont want to pay too much for them.

It all depends on how old they are and what kind of shape there in?? Most times I'll ask for a picture or try to see if for myself.
