No, I would never buy a hybrid. I do not support hybridization in general and would be loath to even buy a non-hybrid from a breeder who sells hybrids.
I'm not so shallow to judge a bird just by its outward appearance, but going off the assumption that most hybridization is done for that sake - I personally think most hybrids either look like a muddied mishmash of colors and/or physically disproportionate. Or they appear so similar to one of the contributing species that I really don't see the point, aesthetically.
For crying out loud, they're already gorgeous exotic animals. How much more ~*~unique~*~ do they have to be before people are satisfied?
All that said, I do recognize that it's not the bird's fault. As others have stated, should a rehomed hybrid I clicked with need a home I was able to give, I might consider it.
