Good, Affordable Travel Cages?

[Chia Pet]

Hi, I'm trying to find a good, affordable travel cage for my pet rats. Right now, they have the Midwest Critter Nation Deluxe cage, and while I am very happy with this cage, it's a bit hard to take apart and put back together. I recently moved into an apartment for college this year, and for breaks, I'll have to take my rats back home with me. I was wondering if anyone knew of a good, cheap, and preferably small (no wheels if possible) cage that I could keep my rats in for no more than two weeks at a time?

I use the smallest size of this cage: https://www.petsmart.com/small-pet/...are-small-pet-habitat-color-varies-36513.html
It is a bit large for a travel cage, but it has a deep base so bedding doesn't fly out, and it has room for a few small, light toys.

Some people use cat carriers as well, here's one that seems adequate: https://www.amazon.com/gp/product/B...O5OS8&linkId=1f49aa6426537daff67cb9080a8ec190
