Welcome!! So nice to hear you're getting a bird!
I agree, if you live in an apartment, a sun conure may drive neighbors crazy....they are loud, but most importantly, they are loud OFTEN.

They love to use their voices.
Green cheeks are great too, but tend to be bitey, in my experience..... remember that ALL species will have its pros and cons. Get familiar with them and then try your best to rule out whatever cons you are not willing to deal with or want. The rest is all determined by the individual bird. (not all fit their reputations)
Have you considered a cockatiel? These are fun loving little birds that brighten up any room with color and a cheerful spirit each day. They love to sing and play and are a wonderful start to keeping birds....especially if you want to satrt off with something that is handlable.
Green cheeks are awesome, cute and snuggly....but watch your fingers. not as screamy as most other conures tend to be. Just happy cute little guys.
Quakers and Senegals are wonderful first time birds too .... especially the quaker and it comes highly recommended as a first time bird. Both are fun loving, senegals can be a little more screamy ... but not typically as much as a conure. Quakers become good talkers, are playful and affectionate, and just the right size for apartment living.
Can't say much of anything negative about them.
Anyway .... there are a few for you to consider that would be a nice choice. Keep doing what you are doing by reading and asking questions....soon you'll have a very nice bird at home with you.

Good luck
