Powder coating runs around 200$ for a set of four here. Paint for it, I would imagine couldnt run you more than 50$ if you did it yourself. I have painted a set of ralleys before and it did stick well though, I got my impala SS wheels being powdercoated anyways because a relative does it as a side business and helped me out. I have always had good luck with painting wheels though as far as it staying on there.
