The tanks alone are reasonably priced for what you get. The stand is very crappy MDF, not worth much at all, I did lots of work to try and see if I can keep my stand lasting for a while. The skimmer is _okay_, and the return pump is crap. I modified my sump to make it to my liking...and had to expand the bulkhead hole in the tank to fit a 3/4in bulkhead/
What I am trying to say, the reason you get a lot of stuff in the package is because the stuff you get is only so so. In most cases you get what you pay for.
I don't have any regrets with my setup, but don't expect the same quality as a lot of more expensive setup's.
