Is space an issue for you? I personally use songmics grids from Amazon as my boys palace is huge and cost a fraction of the price even when you add the cost of the flooring. They have two full levels and the whole set up cost me less than £80. In regards to the cage you are looking at, what are the measurements? How many piggies? Boys, girls or both? Someone will be along soon who knows how to link you to the guide.
