CowBoom offers the used, 4th-generation (previous model) Apple iPod touch 32GB MP3 Player in Black, model no. MC544LL/A, for $139.99. Coupon code "Touch10" cuts it to $129.99. With free shipping, that's $105 under the lowest total price we could find for a new unit, although we saw a used one for $5 less in December. Sales tax is added where applicable. This current-generation iPod touch features a new high definition Retina Display, 3-axis gyro, iOS 4.1, front- and rear-facing cameras (the latter capable of HD recording), FaceTime, Game Center, and more. Offer ends January 31.
