Any thoughts on the Reef Keeper Lite?

I was thinking about getting one about to buy timers, JBJ ATO system, and my coralife digital temp gauge is acting funny. I figure buying all that would put a good dent in the cost of the Reef Keeper Lite. Any experiences good or bad?
Anyone that has a controller I'm sure would recommend one. Just make sure that you are happy with what it can do. I believe the RKL is limited to 4 modules.

I love my RKL and will be adding more to it as my tank expands!
