Also I found the Duna Multy on the zoomalia site you linked above
You won't get a cage costing less than that really, that is suitable for a hamster. And it's a very nice tank style cage. If you can afford it, it's better than the bin cage option above.

Here are some examples of dwarf hamster set ups in the duna multy. First couple of rows of pictures.
