I recently purchased and received the Ferret Kit 100 from USA Amazon. It's on the large end for hamsters. It's tall as well wide and long so one would do well to get Chinchilla ledges to attach. Or make extra platforms and have safety nets for hamsters who are cage climbers - just as hammocks - to catch a free faller.

I just made a video tour of my set up of mine today (currently still in progress).
It's dimensions are 39'' D, 21'' W, 25'' H
Easy to put together. Comes with two heavy duty plastic tubes big enough and then some for Syrians. A ferret litter tray with hooks so you can hang it up as a second level if you wish. A water bottle, food dish, and that plastic white shelf.
