You can search and find such list through google, I used etherdelta, waves dex and one desktop dex I forgot its name. I think if you are interested in them you should really look at oax project.
google in the general search gives out also phishing sites, now all chats are full of people who have paid for the carelessness
I know you are aware of Idex and FD/ED, but currently there aren't any other decentralized and working exchanges. Let's hope that ADAE or CORBIT will change this in near future.
WAVES DEX is even worst.
