Cage Advice Needed on Cage for 2 boys

Okay, so once again, someone has asked me to take in 2 boys because they just need them gone. Previous people have asked me to do this but changed their minds last minute. So, if this happens, I have 2 options for a cage for the boys. I have everything to make a 2x4 C&C cage or I have access to 2 midwest guinea pig cages for free. Which would be a better option? I was going to buy the coroplast for a 2x5 base but the store charges $48 without tax and the closest place to buy a sheet of it is 2 hours away and it is a huge hassle getting it in my car (I have done this before). Since, I will be trying to find a new home for theselittle guys, I would rather not spend money on a cage. So, I am stuck with a 2x4 C&C or 2 midwest cages. The midwest will provide a lot more space than the C&C but, are they considered okay cages?

PS If anyone has a 2 (or more) midwest setup I would love to see a photo to get ideas. Thanks!
