I see this is an old thread, but I hope someone may be able to add to the conversation. Freedom Cage looks like the best one to me. I have been in email contact with the owner and asked for the email of past customers. One of the emails was extremely detailed and praised the cage highly. With respect to customer service, since the owner is basically a one man show, service might not be on par with other companies. He's very willing to customize to my specs.
