I think we're still 3 years off on LEDs being the right power in the right configuration for the right price. I have the Sundial 36" T5 4 bulb and it's a decent fixture. It's a bit cheaply made, but does deliver alot of light, 2 timers and moonlights with low profile. The stock fans are really loud, I took the light apart and installed two Silenx fans as soon as I got it. Made it dead quiet. Those cost around $30 for the pair.
One of my timers acts a little funny from time to time in terms of shutting off, but only on occassion. I kinda miss the metal halide look so got another Current fixture, an outer orbit one, with 1 hqi lamp and t5s to supplement, to have a different look. But for the price, the sundial will do you pretty good for awhile and you can set it right on top of your tank and run it with a canopy or no canopy. Also the stock bulbs are just pretty so/so, you'd do better replacing them after awhile with some ATI aqua blue specials, blue +, and/or actinic bulbs, maybe fiji purple, mixed to your light color preference.
