upgrading skimmer; input please...

I took a better look at the Deltec APF600, now the J&L Aquatics website calls them an "in-sump" skimmer but according to the Deltec website, you cab set them up externally...
Now Euroreef's RC series can also be set up outside the sump so I guess I'm comparing between the RC135 from Euroreef & the APF600. On first glance the design seems pretty much the same. I've heard such good things about both products but never owned on myself. Hmmm; more reading is in order I guess.
