I started a 150g SPS dominated reef around 6 months ago and have gone with high end equipment for the most part.
Lighting - 1.5m Giesemann Aurora Hybrid
Skimmer - Reef Life Support Systems DB10i
Flow - 4 x Vortech MP40s + 2 x Xaqua Xin-outs
Filtration - Zeovit
However that's my personal preference, as I said in my previous post there are many ways to achieve the same thing. Some prefer MH, some T5, some LED, I've just changed from LED to a LED/T5 Hybrid. Some prefer Zeovit, some GFO, some algae scrubbers and some don't use any filtration apart from live rock, although I'd suggest these people are in the minority.
A lot will depend on your budget, I could have gone with a larger tank with lower end equipment, there seems to be a mentality of bigger is better with this hobby but I sacrificed a larger tank for higher end equipment, at the end of the day size influences fish choice a lot more than coral choice.
