I just bought and re-flashed an ASUS RT-N16 with TomatoUSB (Shibby fork) last week and it is a great router. For me it has great stability and range. I had previously used Tomato on an older router and liked it so I stuck with it. You can use the ASUS recovery mode software to directly flash with custom firmware images. My understanding is that because it has this special recovery mode it is virtually un-brickable.
