So I'm looking at cage options, the only issue is that I live in New Zealand so the options are super limited. I'm looking at three different options, one wire cage which will cost $50 https://www.thepetcentre.co.nz/small-animal/hutches-%7C-housing/3-lvl-mouse-34.5-x-28-x-64cm-m3/ekom3.aspx This one from amazon which will cost $80 https://www.amazon.com/Kaytee-CritterTrail-Level-Habitat-Pink/dp/B000HHM6PS/ref=sr_1_25?s=pet-supplies&ie=UTF8&qid=1511135504&sr=1-25&keywords=Kaytee+CritterTrail and this other one from amazon that will cost $220 but looks really good https://www.amazon.com/Ferplast-CAGE-FAVOLA-BLACK-Hamster/dp/B0133LNVAS/ref=sr_1_26?ie=UTF8&qid=1511085761&sr=8-26&keywords=mouse+cage As they currently only have males at the pet store, I will only be able to get one at this stage (or two if I buy a second cage). I am just wondering if it would be worth spending $200 for just one mouse, or if the $80 and $50 ones will be fine with some adjustments. I spent about $300 on a cage for my rats, so I'm not too worried about the cost. The cheaper options make it a lot easier for me to buy more than one cage, but I'm not sure if I have the space for two cages as I won't be able to put them right next to each other.

p.s I am a sucker for spending too much on my pets, pls help
