Another upgrade - looking for input

[xnmuller]

As many of us have been doing as of late I am contemplating an upgraded of my lighting from the halides and power compacts I currently run (4x 96w PC & 3x 150w MH) to LED and I am looking for all those early adopters' input. I run a 135g tank 6' long 20" deep and 20" tall with center overflow. Currently the rock is set up in two islands on either side of the overflow. I have a mixed reef going with some LPS, softies and some SPS set up high. After my initial trolling of the forums and blogs and research on line I have decided to shortlist the following LED fixtures;

1. AI Sol (probably need 3 can I get away with two - one over each island)
2. Reefbrite XHO (probably need 3 can I get away with two - one over each island)
3. Vertex Illumilux (how many of these would I need 2 or 4)
4. Apollo Solar Blast Ultra (how many of these would I need 3 or 5)

Why these 4 you ask - chiefly they seemed like the best bang for your buck. I also considered Radions and Orphek, but honestly they just weren't in the budget.

Now I turn to you. What are the pros the cons, your thoughts, your advice, please and thnak you in advance? I think I'm leaning towrads the AI Sols.
