If money is an issue, get A nac6. For the $50 more I would get a nac7, cone skimmers are much more efficient.
If footprint is important, the nac6 will fit in more places than the nac7
I wasn't aware that this had been proven so definitively re: cone skimmers. My impression was that recent research is showing no significant difference between cone and cylindircal skimmers.
