Kraken.com is another 'big' exchange most use, you can find some credible ones from Ripple to be fair, but be prepared to do some verification (Kraken is quick).
localbitcoin, verification is minimal, as you'd want given bitcoin has a very specific and widely known use of it, unless your a weird cunt that buys pizza with it.
I went with Bittrex, it's not the best looking but it works great. Also when using certain apps and the API key from Bittrex, I don't even have to use their website itself.
