Why not just use clear plastic tubs with lids, and then use sponge filters, which can all be run off the one air pump? Then all you really need to buy are heaters for each tub.
This method seems quite common for breeders of guppies, and I imagine it would prove much more cost effective than going out and purchasing aquarium kits.
