I'll reply. Buying a giant isn't "in my opinion" like buying a BP. There are several things to consider.
1. The overall life of the animal. You will have to care for it the entire time.
2. Giants aren't as easy to sell off if your situation changes so you need to be prepared to sacrifice if needed to care for it no matter the situation.
3. Will you be able to handle it when it gets bigger and you have to clean the cage???
If you have considered all aspects of what you are doing and still believe you can handle it then by all means buy it.
However remember this isn't a toy you can put on a shelf when you are tired of it, or can no longer afford to care for it. It is an animal whos care is being put in your trust.
