MacFarm:

I think your idea is great, and have never thought about using a back-up camera...Duh!  I should have thought of that!  Great going!

I'm like you, or who ever said 'just because it has ag .... on it doesn't mean a whole lot' (to me).  I think the ag cams have some anti-vibration measures built into them, and they would probably last a while (and they're probably worth it); but I sure like the idea of a $75 camera (with free shipping, too!).  BTW: Some of the cameras on Ebay even have 'night vision' built-in.  I wouldn't count on it being Gen. 2, or anything, but it would still be nice.

Thanks again.  Still dont know why I did not think of that...
