Wondering if I should just bite the bullet and get the ND-BC5 or 6, or is there another camera that is superior or equal to the performance, including night viewing capabilities?

 

I'm not up to speed at all on these cameras which is why I ask, will be mounted on a GMC Envoy. The smaller the better for aesthetic reasons.

I am not up to speed on the ND-BC5 but I just had the Boyo VTL375 installed on my vehicle and I am very happy with it. The VTL375 is built into a license plate frame that is strong and will not bend. Works great with my D3.

Good luck with whichever you choose.
