Just my uneducated opinion but it seems pretty pricey for what you get.
I purchased a 48" hood from Amazon that houses one 48" bulb and 4 other incandescent or whatever screw in bulbs. ( I was using LED tip it got colder and I needed a bit more heat).
3 separate controllers as well.

But the hoods from Lightyourreptiles on here seem pretty stellar from the reviews if you are wanting additional fluorescent capacity. The one you linked didn't even appear to have the bulbs.
Once I get moved next week I am ordering one of the 48" ones from them so I can have more light penetration for plants. Currently I have ceiling spot halogens that give me lots of extra light my I am moving away from them on Thursday.
