Keep in mind that the Stacker News wallet is centralized, so it's a good idea to take control of your sats by connecting your own wallet. Also, Stacker News is moving towards a decentralized, self custody model. The timeline is unclear, but you might as well get a head start.

Regarding fees, I have been both zapping and receiving sats to my own node for over a week now. It's pretty seamless, and I don't pay fees because I opened a channel on my node to stacker news. You may opt for an even simpler solution that might cost you a few sats. It's your choice.
