Newegg offers the refurbished 4.6-lb. Dell Latitude E6420 Intel Core i5 2.3GHz 14" Laptop, model no. NE5-0034, for $232.99 with free shipping.

It features an Intel Core i5-2410M 2.3GHz Sandy Bridge dual-core processor, 14" 1366x768 LCD, 4GB RAM, 128GB SSD, DVD burner, and Windows 7 Professional 64-bit.
