Got a few questions for anyone who has experience with Vision cages, specifically models 400 and 600. How do you guys like them overall? What are the cons to them? I was trying to look at them and but I cant really see if they are flat enough on top to mount RHPs. How is the humidity retention with the huge screen vent in back? I was pretty much sold on picking up a couple AP T13s or possibly T10s but now i'm wondering about the Vision cages because they are a 1 piece unit that is cheaper and larger than Boaphiles. Anyways, for you guys who have had them, how did you like them.
