Since the DSi was discontinued in 2011, "best" depends on whether you prioritize price, condition, warranty, or convenience.
| Source | Pros | Cons |
|---|---|---|
| eBay | Wide selection, competitive prices, buyer protection | Condition varies; shipping costs; potential for fakes |
| Amazon (Third-party) | Convenient, return policy, refurbished options | Often overpriced; "New" listings may be old stock |
| Local Game Stores | Inspect in person, may offer short warranty | Limited stock, higher prices |
| Facebook Marketplace / Craigslist | Lowest prices, local pickup, test before buying | No buyer protection; safety risks; "as-is" only |
| Thrift Shops / Pawn Shops | Occasional bargains | Rarely tested; no returns; condition unknown |
Recommendation: For a balance of safety and price, buy a "Refurbished" unit from a reputable seller on eBay or Amazon with a 30-day return window.
