If your friend is not going to be interested in taking a bird to the vet then I suggest none of them!! All birds no matter what the cost need a vet checkup. They need one when they first come home unless it can be guaranteed with paperwork that they just had a checkup and all the results. Then they need a checkup every six months to a year even if they are healthy. If they are not healthy tbey could have very high bills even up to the 1000's of $$$$. Not eveyone is going to want you to return a bird because you don't want to pay vet bills. THat being said!!
Cockatiels can talk, they can be playful life expectancy around 30 years depending on care but this seems to be average listed in most publications I have. The only way they live this long is with vet care and knowledge before buying a bird not after!! They need a good diet, proper size cage and lots of attention. They will not start talking immediately or automatically love their new owner it takes a while no matter what kind of bird you get.
Please don't let your friend get another bird until he is ready to take on the responsibility of all costs no matter what the price of the bird. If you get a bird for free as a present does this mean it needs no care because hey it was free?? No it doesn't!!!
