I have zero issues with my Pro-Line cages. None at all. I actually prefer not having that post in the middle and one large drop door. I like to put in and pull out my perches and other decor without hassle. I think the HDPE plastic is better as well. Monster uses the same plastic and they are prebuilt and have thermo welded seams and ceiling supports.
I've been to the actual facility where they are built and the retic area Matt has.
They have a brand new facility they just completed work on that I'm excited to see.
But make no mistake, Ed Lilley is a hell of a good guy and his cages are made well, easy to assemble and do what they are designed to do.
I certainly don't have any qualms with other types of caging, but all 3 of my Pro-Lines are excellent and I'd recommend them to others. As a matter of fact there are very few cages that I find more attractive than my Pro-Lines.
Even still, for the larger size and feeding response of a retic, I am going to get double doors and something local to save a lot of money on shipping.
