Anyone know anything about price feeds?

  • Barclays London
    • Capital Market Services

    • FX Dealer Direct

    • Forex Capital Markets (FXCM)

    • GAIN Capital – FOREX.com

    • Global Forex Trading

    • MB Trading

    • PFGBEST

    • Saxo Bank - Copenhagen

These are the feeds that I can choose from, does it make a difference who I go with? I will be trading with Dukascopy.
