I went the LED route as well, about a year ago right when the "Full spectrum" lighting was taking off. My corals grow very well and I have some good colouration (although I had only set up the tank with the LEDs in January, so it's still new).
That said, one of things I haven't considered was resale. It's going to be almost impossible to get any kind of return on the kit I purchased. Sure, I saved $150-250 (used v. new) compared to a similarly powerful AI unit (with full spectrum). That said, if I need to upgrade my lights ever, I think it would have been better long-term to get a pre-made unit.
Anyway, just my $0.02. I know I saved a bunch off the hop, but I wonder how the savings will compare long-term.
