Radio question/help

I am putting the finishing touches on my 70SS, I want to install a good radio/stereo. I want to retain the orginal look, with the updates of a modern radio, mainly I-pod ready. I have read some posts, which indicate two companies, Antique radio company and Authentic. Then I saw in NPD the "same" radio with the same costs. My question is are these the same? Any one had any experience with these and are they the same? The posts I read there was some time lag between ordering and receiving. Want some tunes! any help would be great thanks.
