I've had three of the AI Vegas on my 125 gal for about a month now. Love them, they really put out the light. There are a couple of places locally where you can pick up AIs. Since you really can't find them discounted on line, you might as well help out our LFSs. Neptune's down on county line and university carries both the Sols and the Vegas. Fish Palace over on Havana south of Parker carries the Sols. Also later this summer AI will be coming out with a new controller that should really kick ***. They are just about to start beta testing it.
