There are experienced hobbyists who run skimmerless reefs. It is a matter of debate to use or not use a skimmer. Skimmerless systems still feature elaborate system designs and frequent water changes. So what you have heard is a topic of debate. Both system designs, if followed correctly are successful.. Some of these issues are addressed in The Reef Aquarium Vol 3.
The majority of reefers, as I, choose to use quality skimmers with a DSB or plenum filtration system. Trickle filters are also being faded out as the new trend is to add a sump-a-fuge. My gallery has such a design for building one. It may give you some ideas.
Tillerman, my best advise to you would be to invest $80 in the book. It is a must have for anyone who is currently setting up or remodeling a reef tank. It addresses issues on design, water chemistry, plumbing, electrical, etc. It is not like any other book you will find for a "new aquarium." It is more scientific.
