Valedictions: Yours Truly

Wikipedia's article Valedictions is good. It talks about differences between England and America, and about French, German, and Hebrew valedictions. I don't like "Yours sincerely", because though I suppose I am always sincere, it seems inappropriate for describing the contents of a typical letter. "Yours truly" is always apt, nicely conventional, and sufficiently uncool. Cheers, Best Wishes, and Best Regards have their places too.
