I agree with souffle, for £40 you can get a 160x30 cage/aquarium from ikea, so I always use that to aid my decisions on whether something is worth it.

There's a bargain cage thread where people post cages from ebay which are cheap, although not all of those are suitable for a syrian.

But ideally you want something 70x40, minimum.. but 'indoor guinea pig cages' (the zoozone 1 or two, or rody rabbit etc) regularly come up on ebay, and although they need meshing, they're usually very good value, especially since they're often pick up only, so you don't always have many people bidding against you.

Good luck finding a cage, I have plastic cages but the insides are all natural, which looks fine to me.
