I agree with Athena in that I also wouldn't get a 'starter' bird...because most people end up with a bird they're less interested in once the novelty wears off...
In hindsight...get the type of parrot you really want...and you know what that is - you're leaning towards one.
If you weren't doing research, I might suggest differently, but if you're doing your homework and are in it for the long-haul, then go ahead and get the type of parrot you really want.
Again, it might not turn out to be the right decision...but it might end up to be 'more' right than going the safer route.
Part of me wants a macaw. But I was scared I'd find one too big and too much work. In hindsight, if I had gotten a macaw...I might have been satisfied with the one parrot (plus the 'tiels of course)...who knows? Work-wise, it would be the same as what I'm doing now, or even less...
I have no regrets doing what I did...so it would have been more of a lateral decision vs. a better/worse one...
