Hi,
Haven't been on this site in years, but I found a Vertex IN-180 in sump skimmer while cleaning my basement. It could use a little cleaning, but i plugged it in and still works. No Idea what an older skimmer like this goes for, but I will just ask $40. It is the skimmer I used in my tank pictured in my signature.
Here is a link to this discontinued skimmer for the information and sepcifications:
