DIY will offer you more options if you're up to it. There are more and more people making their own lights and more and more kits being sold to do so. Many hobbyists that have built them offer fair rates to build them for others, something to look into if you have an active local reef club. Where I live, everyone is going LED. My husband has built some units for local hobbyists, but he's one of many, many hobbyists doing it.
As for premade fixtures, I think Acan Lighting have the nicest units. My local reef club holds their meetings at Acan's headquarters. I've gotten to see all the units first hand and talk extensively with the owners. They are the most helpful guys out there, and offer warranties and excellent customer service.
The Aqua Illuminations SOL unit is also a nice fixture.
