I've got a Cambridge for Rolo, our LH Satin - and I think it's brilliant. I think it gives a pretty good space on the whole with the levels and there's plenty of space for a good Syrian-sized wheel - plus lots of climbing opportunities, Rolo climbs all over it!
What I find really impressive though is the quality - it's very well-made and just feels like a good cage - all of which makes me really want to try the Savic Hamster Heaven as I hope it will be same quality-wise, just bigger
Here's a picture of Rolo's Cambridge:
