I don't actually remember, I think it was something like $250. And that was through an agency, so surely it could have been even cheaper if I understood enough Russian to buy the ticket directly. There are first class rooms as well, for even more comfort and privacy. I can't imagine they'd be bank-breakingly expensive either.
