Skipper, just fyi theres a new product out there, called sapphire nano skimmer, google it, ive heard great things about it. BTW a nano-cube will run ya about 90-150, depending on the size or the light config, theres a new Metal Halide model, that includes a skimmer of a 28 gallon nano cube available direct from JBJ or you can find it if you google nanocustoms. Bio cubes are unneccesarily more expensive IMO, and harder to mod than nano-cubes, im not sure about the Aqua Pod, or the Red Sea max, and I HIGHLY doubt that its 699 euros, thats near 800 USD theyre more around 300 euros, or thats what ive seen.
