Nintendo Repair or local shop?

My Switch Lite recently bricked with a 2101-0001 error and I’m debating what to do about it. My main concern is saving my 400 hr ACNH island, so am debating between sending into Nintendo for repair or getting service done at a local shop. Local shops are at least $50 more so I’m trying to get a sense of how often people send into Nintendo and get back a totally reset Switch and lose all their data. Anyone got any success stories? 🤞Or should I not hold out any hope that I can save my island (I don’t have island backup turned on)
