I agree, get the hamster heaven, it’s a great cage if you block of the tubes (with the blockers provided) & remove the penthouse, then you can put your own house, shelves etc in, it’s just about high enough to accommodate a 9” wheel although you do need to have the substrate a bit less deep where the wheel goes, I make a little shelf for the wheel to stand on.
Joining cages with tubes isn’t the same as having one larger floor space so one bigger cage is always better, you can often end up with them sleeping/peeing/storing food in tubes too which is a real problem.
