Dell has the Nintendo DS Lite in Metallic Rose for only $103.99 after 20% off coupon code Z0WPL1J0CC3W47 reduces the standard $129.99 price. The coupon is currently valid through 3/25 but may not last that long. Plus, shipping is free. Sales tax is charged to most states. This is the best net price I've seen on the DS from a reputable store. Of note: pay with a Dell Preferred Account (find this under "payment type" at checkout) and you'll get an extra 3% off.
