I recommend Cryptsy, They have just removed trade fee's, which is huge if you plan on heavy day trading.
They are having to support more verification's for withdrawals because of new federal regulations. Even so this just makes it more secure.
I find this still the easiest exchange to get into with cold feet and learn how things work. They have a live user chat that is open 24/7 you can chat directly with employed moderators from within Cryptsy.
They are currently trying to offer fiat debit cards that work in conjunction with your Cryptsy account, they need a few hundred more to join for it to begin.
Currently we have experienced no longer than 36 hours for a BTC withdrawal, this is only recently as the laws have become more strict and the amount was third tier so that is not too bad.
