I'm not sure what you mean by your Nikon View pooped out on you - have you tried to re-install it? I haven't ever tried it, actually, so I don't know what could be causing the problem there.
As far as free goes... you can just copy the files directly to any folder on your Mac that you choose directly from the finder or desktop after inserting your card reader or connecting your camera - just like from any external disk. Totally free.
Then there is the free software by Google for photos called Picasa. It works a lot like iPhoto - and I use it quite a bit. Just download it, and set it to be the application that opens when you insert your photo sd card, or CF card, or connect your camera. Works exactly the same as the Nikon software, or iPhoto as far as importing your pictures from the camera. Once you set it as the primary app, it will just launch automatically when needed.
