FXCBS broker is rather new (they were opened online in the end of 2007) however it became very popular recently after fapturbo introduced them to the general public. FXCBS is one of the rare brokers that offer really good trading conditions - honest ECN environment, variable spreads which can be as low as 0 and fast execution.

They somehow manage to keep low spreads even during the asian session, that's why this broker is very good for fapturbo and other scalpers. Take a look on the spread history on EURGBP. The spread is as low as 0-2 when other brokers keep it around 5-12 during the asian session

The only bad thing about this broker is they currently don't accept US clients, however i talked to mr. Sanjaq and he told me that soon they are going to accept US clients as well when they finish the regulation process

Update June 2009 Good news - FXCBS lowered min. deposit to $1000 and started to accept US members!
