This is a link to a guy that summed up the pros and cons of different lines of PVC cages who has been in the business for a long time so it may be informative for you. I decided to go with proline because I wanted to keep the cages for a long time and I like the drop down windows compared to the sliding glass doors. I have heard a lot of good things about animal plastics too and a lot of people like the boaphiles. Happy hunting!
