Good setup for hydro?

Below is a link to a hydro setup on eBay. Would this be something appropriate to use? Also, what do you guys recommend....a bunch of smaller plants or a few large ones?

Whoops, forgot to provide link... 10 PLANT DRIP HYDROPONICS SYSTEM + HYDRO CD HYDROPONIC - eBay (item 200159341728 end time Mar-01-08 18:43:56 PST) On the same note...which is considered best? Ebb and flow Drip Constant bubbling ???
