Just a word of warning due to the experience i have had. I bought a 150cm from Zooplus a few weeks ago. It arrived with the bottom basin, which is plastic, smashed. sent a new one which arrived yesterday, and was smashed even worse. I would avoid this company at all costs. The goods are shipped from Holland (the company is German), and the only protection the cage had was a bit of cardboard.
I have hashed together a repair of the cage, and if it hadnt been damaged I would highly recommend it.
It is HUGE, plenty of room for my 2 boys. They sell them on Amazon, so I would go there if this is the route you choose to take. I have bought from Amazon loads and never had a problem. Cage is a bit pricier there, but worth it if it arrives intact.
