Does anybody have a "truck camera"? Similar to a truck gun except a camera. Basically, something that strikes a good balance between being a capable camera, so you can always have a DSLR with you, even when you don't, and also being inexpensive enough that you won't miss it in case minorities get inside your vehicle.

I'm sort of thinking that a Canon 50D could do the trick. The body is only $150, but the resolution is pretty shit. The 60D is obviously much more modern, but $100 more expensive and I don't like the 5 way controller in place of the AF joystick.

I don't want to get hung up on brand. Are there any good Nikon, Sony or Pentax camera bodies worth considering? A part of me kind of likes the fact that you can get Sony NEX bodies for really cheap, but I hate the interface and lack of physical buttons.
