I haven't seen any of the current remastered versions of TOS yet. I bought virtually all of the originals on VHS and then bought the first DVDs when they were over a hundred dollars a set. That probably adds up to a thousand dollars. Anyone wants to give me remastered blu-rays, though, I wouldn't say no out of any purist impulse.
The entire TOS bluray set, basic, goes for very little these days. I got myself the 50th Anniversary set last year with TOS-R, TAS and the movies for £120, which is about $200?
