Coinex all the way. Cryptsy fees are at least 2-3x higher and they tax when you place the bid. Coinex taxes the transaction.
This post is just plain wrong. I advise people to check with the exchanges to get the facts.
As of right now:
Coinex is 0.2% sell and 0.2% buy
Cryptsy is 0.3% sell and 0.2% buy
Cryptsy does not charge for placing orders... the fee is a percentage on all/portion of the transaction *filled*. Like everyone else.
