Are these new episodes available on DVD in the US fairly cheap(<$45)?
Well, if you're referring to the new episodes starring Christopher Eccelston, the answer is, you'll have to wait til July to get them but the list price is $99.98. If you go to your local Best Buy, however, you'll get it for a certain amount off the list price.
The good news is, however, the Sci-Fi Channel airs the show starting March 17 Friday nights at 9, so you'll have a chance to see
what you're buying before you go spending an arm and a leg for the DVD.
EDIT: Ol' Peculiar, thanks. I knew it was March but not March 17. I will watch it, but I haven't tuned into the Sci-Fi Channel to see their promos for it. I looked on their website though and nothing. And number 302079, after you watch the show and the DVD comes out in July, go to Best Buy. They sell DVDs cheaper than their list price so you might (emphasized might
) be able to get it for the amount you said.
