I just realized Google actually provides bitcoin conversion (search for "convert btc usd"). Preev also offers conversion for litecoin, peercoin, and dogecoin. Such simple. Much upvote.
@rrhoover "Such simple. Much upvote" needs to be a bumper sticker.
I use Preev daily every morning. It's simple, fast and easy to use.
