NBC.com has all 8 of these shows as Season 2 for Free!
I'm not sure if they match the DVDs, but I found all of Season 1 and Season 2 of Battlestar Galactica listed as "Battlestar Galactica (classic)," as opposed to "Galactica 1980" or the 2004 show.

It's not as bad as I would have thought it was by all the negative comments about it, it is kind of cheap and campy, but sort of in a good way.
