You can get this sort of flight cage style and size in most brands nowdays. Standard flight cage 32" wide x 19" deep (sometimes 18") x 64" tall. https://www.amazon.com/Wrought-Fligh...cage+for+birds
The Prevue Hendryx 040 and 050 that FaeryBee uses and loves, are nice cages too. I don't have one, but I have a smaller cage that I'm currently using as Chip's quarantine cage by Prevue Hendryx, and it seems like a pretty decent brand.
