Going from a 55 gallon to a nano. Any suggestions for an "All-In-One"?

I had a 55 gallon tank for two years, then we ended up moving and I took her down.  Lately, I've been getting the itch to get back into the hobby, and I was seriously thinking about a nano reef tank that I'm going to keep at my business. need a lot of attention parms change fast, especially salinity, IMO not good location.

I really don't know much about nano tanks, other than the few Google results I got that brought up the Oceanic BioCube HQI 29 gallon all in one set up.  It looks like a pretty good option, but there aren't too many independent reviews of that particular unit. I always just set up a smaller version of my large tank,  piece my equipment, replacing them is easier when they break down.

I would be more than happy to listen to any recommendations of what any of you guys may have, would like to have, or something I should stay away from.  I probably have a budget somewhere in the $750 range to get started, and I really want to be able to keep a nice array of corals (both hard and soft) and some clams.  As far as fish maybe just a clownfish or two, and some CUC. Could be done the light is the most expensive part, look into the Ecoray 60D LED.

Thanks for all the help and suggestions!
