Their ok. EZ trader is OEC they just white label it.
If you look back OEC had some serious issues in the last 1 1/2 years but I believe they are resolved. I hope so I am funding an account their in a few days.
Tried them a few years ago. Prices were ok, lousy customer service. At the time they were also white labeling the (horrendous) Transact feed.
You can do better.
