Shopping Cockatiel Cages?

Finding a sand-up, high quality Cockatiel cage can be quite challenging.  Cockatiels are one of those species of birds that falls into that gap between small birds and medium parrots.  They are larger than Parakeets, but quite a bit smaller than Amazons & African Grey Timnehs.  Just keep in mind that virtually any medium sized stand-up cage will work well for Cockatiels, but you just can not get a cage with bar spacing that's wider than 3/4".  Ideally, your Cockatiel cage should have a bar spacing of 1/2" or 5/8", but you can go as wide as 3/4".
