I've been using a new exchange for the past couple weeks called Breakneck.trade -
www.breakneck.trade. Nice features, no fees and a growing community make me like it. There is no lag at all in trade execution and 50 some coins are offered.
I wanted to post my referal link here but since that is not allowed I'll just give the site a boost. Hope that is allowed.
