I can't link specific listings, but here's how to find a **good deal on a DS Lite** safely:
Look for lots: console + charger + 3–5 games + case. Often cheaper per item. Resell extras to recoup cost.
If you just want to *play* DS games: buy a **DS flashcart** (R4i Gold 3DS Plus, EZ-Flash Omega) + microSD. Plays ROMs/homebrew on any DS/3DS. Legal for backups of games you own.
Warning: Avoid "refurbished" listings with stock photos. Ask for real pics. No charger included? Factor $5–10 for OEM replacement.
