Maximising My Rotastak Hamster Cage Investment

If I want a large space for my hamsters to play in, I will have to buy many Rotastak hamster cages. I understand this can add up to be a hefty investment. Are there any cool ideas and ways on how to maximise my dollar spent - so my hamsters can have the best possible home experience of their lifetime?

Interestingly, I came across someone sharing about how he/she put their rotastak unit into a plastic bin in order to give their pet more SPACE to move around in + give his/her hamster the FUN of playing in a Rotastak unit. What a fantastic idea!

I've also seen a photo of someone using Rotastak tubes to link two tubs together for a super huge space for a hamster family. This could be a cost effective alternative to getting a Rotastak cage.

I like how large plastic tubs are. I also love how cool and funky Rotastak hamster cages are - with all the connecting tubes for hamsters to climb in and out, up and down. This would be a fantastic way to merge my two favourite hamster home solutions. :) Awesome.
