I can say this tho, you might be right about the dust, depending on how sensitive you are to it. my brother is allergic to a shitload of things and well.. (he likes birds just as me) but e gets really bad whenever he has cuddled a cockatoo, and well a cockatiel pretty much produces the same dust although in much smaller quantities and most people that are sensitive can get past that by being really really thourough and frequent in their cleaning of the home.
All birds produce dust though, but.. some more than others, som (lika cockatoos) uses a chalky dust to take care of their feathers, others like amazons use a fatty gland for the same purpouse. Since I am not allergic I havn't spent a great deal into looking at wich birds uses what type of "substance" to take care of their feathers, and I am especially not that well read up on the smaller birds I'm afraid.
Now I am actually a big fan of agapornis (lovebirds) couse I just think their so darn cute and they kind of have a big birds face all shrinked down and cartoonized (not even a word I think). And while I am not a big fan of the whole idea of breeding for colors I can not deny that some of the colors these come in is absolutely supercool, such as these:

I mean I have certain species that I wouldn't feel much desire of having as companion birds, some of them are among the most popular ones. And some are on the list of what others would drem of... I had a friends toucan living here with me for a while (about 6 months) while my friend was sick... I harness trained him and took him around like any other of mines and while he draw a lot of attention I figured, I would not want to get a toucan of my own. sure he was all sweet and cuddly but not for me (and yes I know toucans arn't really parrots, their in the same family as wood peckers). As mentioned earlier try visit rescues, if you happen to live in a place such as me where there are NO rescues. try finding communities in real life of people owning birds, and try meet different birds that way. Just make sure that whatever you end up with (if you end up with anything, providing people do enough research a lot of people back out, especially people who had had children that now has grown up and they figure, that they do not want to take on a toddler again for the next decades, and that what having a bird is and the attention they need if kept as single companions, now you can keep flocks in large flight aviaries and such and get past the toddler caring.. but I get the idea that that isn't what your after) anyways, make sure that whatever you end up with, your prepared and know that it will limit your ability to go off for vaccation or even spend weekends somewhere else. It will impact your relationships (sometimes with your bird sometimes with romantic/friendship/family-relationships). Good luck in your research
