What would you get? Skimz SM 121, SWC160, Nac6A, Nac7 or NAC9?

[RuGlu6]

So looks like it came down to a choice between
SWC 160 and Bubble Magus NAC7

both skimmers have same Atman2500 pump, same shape (cone), same air intake.
The only difference is SWC has air intake control but you would want to run at full air anyway.

NAC7 is aprox. 220$ shipped
SWC 160 is $274+tax= $307

Just wondering if i am missing something here?

thank you.
