I would probably go with that one.. My first unit(the 300) had no switches or dimmers(I was one of the first people to get one and it's been a while) .. I would go with that one of your looking to stay with the smaller wattage..Is this the one with the color switches? What are the advantages?

But mine is a bit different(the one I'm using now) .. It's one of the white units that vents the exhaust of our the sides. The advantage, is tailoring the color you want.. My unit, I think I have run the whites only once.. I only use the red and blue channels.. And right now, because I'm actually trying to slow my growth, only the blue..
