My boy is going on 13 and he's, honestly, the easiest bird in my flock. I got really lucky. He's not that loud at all, rarely even screaming and if he does it's just being silly and goofy and in fun and goes away within minutes; he talks clearly and is hilarious in what he says, thanks to growing up in a household of teenagers; he's almost always in a good mood; he's never seriously bitten me; he's not the hormonal type; he not only goes to everyone in my family, he will go to any stranger I hand him to (I even take him to visit rehab hospitals to cheer patients); he's affectionate and will accept petting anywhere (his favorite trick is to do his "snuggle bunny," where he snuggles down right at my chin laying crosswise on my chest and takes a nap); he's learned a variety of tricks and will speak and perform on command, which is really a fun way to share him with others; he will play independently and rarely demands attention (maybe because he gets so much anyway). He's a very wonderful, trusting, well-balanced parrot and a valued member of our family and flock. From what I've read, they aren't always this easy. I'll just be thankful for him. He's a family and friends favorite around my house.
I can't think of any real serious "cons" but I will say he goes through a staggering amount of wood toys. He can destroy a full wooden toy in just a few hours. We make some of them at home but when time doesn't allow for that, he can destroy and NEEDS a wood toy a day. He treats it like it is his JOB to splitter wood. He's a good eater, but Galahs really are easy to spoil. Like Amazons, they LOVE food, and usually foods that aren't that good for them, so that's a constant battle with him. He begs for ANYTHING you make for yourself that he thinks he has coming to him (and he prefers carbs to veggies LOL). And, yes, he's dusty but he's not nearly as dusty as his "neighbor," a Congo African Grey, who is a powder-making snow machine! I guess the only other con I can think of is that he's not really that social with other birds. He's just never paid them any attention. It's just his way.
Good luck on your quest for a RB2. I think choosing a breeder that raises them correctly is probably a huge advantage. I give all the credit for my guy to the parrot-only store I got him at. They have a really great reputation for raising young parrots correctly, allowing them to fully fledge (confidence), wean at their own pace (security), learn to play on various surfaces and with many different objects and toys (bravery and adaptability), and socialize them (friendliness to humans). Just be careful choosing your breeder. They're not all the same.

But I look online a lot for galahs that need rebooking but not to pricey.
