I bought the DSX-MS60 Sony....its the one with the tray. I havent installed it yet but it looks cool and its marine grade...i got mine off ebay for 130.00...Not bad at all,, and i sold my stocker for 400.00 on ebay...got enough for sony and biketronics kit i stole for 100.00 bucks...and a pbr300x4 amp...was a no-brainer for me!
