I like the Savic Rody a lot - it's of a good build-quality, as you might expect from Savic, and it's eminently affordable.
I agree with the comment on the dwarves - which is where this cage is ideal, for the smaller hamsters. There's enough floor room for a suitable selection of toys, and it was deep enough for me to install some tunnels for my boys.
The green section, as in the pics above, forms an ideal little house - my only complaint being the position of the waterbottle, which is exposed at the bottom.
Tupac, who'd decided to nest underneath the bottle, enjoyed chewing as much as the next hamster - until he punctured the plastic, and got a drenching! Cue one ruffled, distinctly sulking, Winter White!
At £24.99, superb - ideal for starters!
