I still think the Sol is one of the best built LED fixtures out there. I think people are selling them to upgrade to newer, thinner, "full spectrum" fixtures. Used Sols are a decent deal at $250-300 used, but I wouldn't spend more than that given that you can get some pretty awesome brand new fixtures for $400 now.
I personally do not think "full spectrum" lights will have any noticeable growth benefit. There is a well established science behind using red lights to grow plants/algae more efficiently, but more efficiently does not mean faster. It just means it uses less power. I think the use of multi-color LEDs serves more to improve appearance of corals.
