Yeah, I think I'll definitely be getting a Silver Surfer in the summer when I finish upgrading his cage (I got him in January and I'm slowly but surely removing all the plastic in his cage that the older owner had given him and putting in fleece, ledges,etc.). The silver surfer is nice too because it takes up less space than the Chin Spin (and 20 dollars less doesn't hurt either).
I've got a question though, I've got the Feisty Ferret cage which is similar to the Ferret Nation in that it has the three horizontal bars on the sides of each level. Does anyone have a ferret nation, and did you have trouble at all attaching it to the cage? Having two hooks instead of more wing nuts kind of worries me.
