"Nintendo DSL" doesn't exist—you're likely thinking of the Nintendo DS family: DS "Phat" (original), DS Lite, DSi, DSi XL. Prices vary significantly by model, condition, and completeness.
| Model | Loose (Console Only) | Complete (Console + Charger + Stylus) | Complete-in-Box (CIB) | Notes |
|---|---|---|---|---|
| Original DS "Phat" (2004) | $25–$45 | $40–$65 | $80–$150+ | Bulky, dim screens, GBA slot. Collectible as "first." |
| DS Lite (2006) | $35–$65 | $50–$90 | $100–$200+ | Best balance: bright screens, GBA slot, compact. Most common. |
| DSi (2009) | $45–$80 | $65–$110 | $120–$250+ | Cameras, SD slot, DSiWare, no GBA slot. Hinge cracks common. |
