$60
Bought it in May 2012 in Germany, have used it there as well as the States since September 2012. Unlocked so you can simply insert a working SIM card and it's good to go.
Overall the phone is in good condition as you can see in the photo. There are a few scratches on the bezel but the surface is intact. Comes with 2GB MicroSD memory card, Boss carrying case, and interchangeable white back panel.
Retails on Amazon for $156.18 plus tax: http://www.amazon.com/Samsung-Galaxy-Ace-S5830-International/dp/B004Z207HK
