We bought a baby Syrian a week ago (6 weeks old) and I feel like I've cocked up the cage buying a bit. 
I had a hamster as a teenager and had a Rotastak cage so went for one again (the adventure one) but it just seems like the opposite of the tardis - looks massive but the poor wee hamster looks cramped inside (and she's got a bit more growing in her yet).
I'm now looking at other cages (budget is a little tight but the poor hamster has the right to a decent home). I'm considering 3: Hamster Heaven, Savic Alaska and Barney Skyline.
Does anyone have any thoughts, experience or comments (or any other recommendations?) We don't have masses of space by the way (hence dithering between the 80cm and the 1 metre).
I don't want to cock up a second time
