L.A.-based iStyle is offering custom laser etching for the iPod, iPod nano, and iPod shuffle, either by mail or by physical appointment at its Melrose Avenue location. The etching is permanent, but can be scratched out or designed over, and does not void the iPod warranty. The service is also available for laptops. Pricing for the etching service starts at $25 for the iPod shuffle or iPod nano; full-size iPods run $35.
