HOB skimmers I agree are worthless, should you get one the Tunzes IMO are best bang for the buck. Then when you get into that range, you mind as well get into the in sump models. I agree w/everyone here, ER are good enough to get the job done, as well as the ASM. But you should save the $$$ and make it worth your while in this category.
As far as Aquabee pumps sucking. They are more efficient than the Sedra pumps, which the ER, and other skimmers use. Aquabees come second to EHEIM in Europe. If you would look at a lot of the high end European skimmers they use Aquabee pumps all the time. Then the higher ends have EHEIMs. They very efficient when compared to Mags, or Sedras. Less energy = less heat.
