When I was originally watching DS all of them looked old to me! But then...I was all of about 13 at the time.
Last I saw, David Selby is still a very good looking man but nowhere near young enough to play Barnabas.
I envy your DVD purchase. I subscribed to the VHS tapes for some time but never got any of the DVDs. I did get the entire '91 revival on DVD though.
