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

Can you please check what is the height of the rising tube from bubble diffuser plate to the bottom of the collection cup neck?
I am considering this skimmer and would like to know what is the size of the mixing chamber.
Also what is the diameter just above bubble diffuser?

There is a new skimmer on the block 2011 Marine color CPS-150 that is very similar to NAC7 but they changed a water effluent tube, made it few inches higher which will make it more consistent in regards to a water level and more stable. looks very similar to a HERO line skimmers.

Thank you so much.
