Hot shoe laser?>

panoguide: the guide to panoramas and panoramic photography
Photoshopping, masking and perspective correction have always been inevitable in my nadirs, but for best results I do my best to minimize the need for them.
Not all nadir surfaces are perfectly level and flat, and if there are unmovable objects very close to the nadir you need all help you can possibly get to reduce parallax problems.
With the camera accurately aimed at the nadir mark using the laser, and leveled using one of these:

at least you only need to worry about maintaining the proper height of the camera, and keeping it still (enough) of course.
For keeping it still I have a solid solution for most situations, for measuring the hight without plumb-thingies within the frame I'm considering using multiple lasers in an arrangement like the British designed for their 'dam-busting' bombers in WW2.

ps. about that 'through the viewfinder' configuration: remember that the mirror of an SLR is not 100% reflective, so some of the light will pass straight through it, not only reducing the luminance of the beam that comes out of the lens, but also straying into areas inside the camera where you probably don't want it to go.
