cypher - it is indeed a silent spinner. I can't remember how old it is, but it spins very easily and works just fine
So, I ended up getting a really cheap deal on a Duna Multy (same size as zoozone 1, about 71 x 46 cm). I originally wanted to get a glass tank, but I will be moving house in september, so something plastic will be easier to move. If he seems bored, I will be happy to upgrade him later.
Thanks for the links, I'll be sure to have a good look
