Good advice from both above...Most people will tell you that Green Cheek Conures are the "Beginner Conures", I guess because they are the smallest and while they're not quiet, they're not as loud as a Sun Conure, Jenday Conure, Crimson Belly, Patagonian, etc. I've had 2 Green Cheek Conures, I now have a male that is a little over a year old. Both of mine were hand-raised and hand-fed by their breeders and they love scratches and are generally very snuggly. They are called "Velcro Birds" because they always want to be with you, on you, stuck to you during everything you do. I love my little guy, he's a sweetheart. A "Pineapple" is a type of Green Cheek Conure, it's a color mutation, and is called a "Pineapple Green Cheek Conure", I'm not sure what a blue pineapple conure is as you said you're looking at, it could be a "Pineapple Turquoise Green Cheek Conure", but if it's not a mutation of Green Cheek Conure then I'm not sure what it is you're looking at. But no matter the color mutation all Green Cheeks are pretty much the same personality wise.
Keep in mind that birds are individuals just like people are, so you may get one that is nothing like I've described, it may not like to be touched or it may be very loud, but in general that's what they are like. I agree with Abigail, it's best to go and interact with some different birds to see what individual birds are like. This is the only way to know for sure if the bird will fit what you're looking for.
