I'd use the DNW-150 myself.
The others are right. Octopus skimmers are a fine machine for the price. They ain't a Bubble King, Deltec, etc, but they pack a lot of value into what you pay, and work very well.
Do you have a sump and overflow? If not, consider getting one if possible as these make skimmer installation easier (and don't limit you to HOB styles) and have numerous other advantages.
