A lots brokers offer ECN/STP access now. Many of them are using MT4+bridge which can markup quotes and trade directly with the trading desk (danger situation , even a huge spike kill your account).
It seems EBS, Currenex, fxall, cTrader should be reliable. Interactivebroker, Dukascopy, Lmax which have run long enough are ok too.
