Thanks guys.

There is a hate thread for IDEX tho > https://bitcointalk.org/index.php?topic=3974898.0;all

I will check out sobit, waves and joyso.
But will give Etherdelta a pass, since... no one is vouching its qualities from this thread LOL.

Are there any quality ones I should pay attention to?
