I currently have the CB6000s but ive lost some parts from it so I cannot use it. Rather than buying another I was thinking of a metal device. Are there any that are around the same sort of measurements as the cb6000s that have decent reviews? A lot of metal devices seem to be a lot bigger and I don't really ant to go with a custom device at the moment.
Go to dhgate, there are several metal and stainless steel devices there, ranging from quite large to miniscule.
You can also get the CHinese-made devices on Amazon. The Bird Cage (my avatar) is a bit too long, but the Jail House M200 is a bit shorter. I've had both (before I got the custom Jail Bird) and they were inexpensive and fine.
My cage (my avatar) is most convenient from the hygiene point of view. No need to unlock for cleaning. Excellent ventilation. No splitting / breaking of cage. A real life long item. I bought it from ebay.co.uk. By the way, most people are against buying Chinese cages. However My cage is real stainless steel & I have no issues in the last 2 years. It's worth a buy.
The M200 is AWESOME, inexpensive, and AWESOME. Had huge problems with the chrome one, flakes ended up lodged where they ought not be. This black powder coated one has served me well, but true stainless steel would be even better!
