look into the audiovox CMOS-1

you may end up paying a LITTLE more than $60 (more like $99), but its a great camera and i promise you its going to be one of the most resilliant ones you can find. you can find it at any best buy or online for $99. guarantee its gonna hold up in the cold (it has no problem in colorado cold)

it also has a reverse image viewer which is very very necessary (most of the cheapies dont have it), otherwise you will see everything backwards and end up backing into everything

it doesnt have a 'night shot', but it does adjust for bright or dim situations. and it fits perfectly in our rear view spot (as well as possible without having the factory)

also, you will have no problems plugging it into your deck (i have done many of them on land rovers and yukons)
