I've been getting all of my cages custom made from cages.net. Although they're not machine made and may have slight imperfections, I have not been more happy with the cages since I started getting them from him. As a matter of fact, I just ordered another 8 cages to fill the last of the wall space we have in our herp room.
I've never really had issues with the LLL cages, other than the fact that they do seem to take a little while to get to the east coast. While they are a little cheaper, I'd rather pay a few bucks more for custom cages that were hand made by a local Florida resident.
