I have the NAC 7 and I love it. Foams really well, solidly built, easy to put together, easy to dial in and the cup is easy to remove for cleaning. :thumb:

They are both great skimmer but Id have to go with the In-180 if comparing the 2. We sell both and we love them both, they are both close in price NAC $249 and IN-180 $299.

The biggest difference between the 2 is the foot-print. The IN-180 is huge where the NAC 7 is very compact. I would post a comparison picture but the NAC are on BO.

Here is a visual of the in-180

We have a Vertex In-180 skimmer and we are extremely happy with it...pretty good skimmer for the price.

I have hands on with both..... vertex seems to be built a little beefier but is noisy and large..... BM seems a little plasticy, but is quiet and has a nice small footprint..... the pumps on both have had issues......but one cant expect too much from a cheap skimmer:wink:
