Which Broker has the best swap rate?

After the global recession that all central banks reduced the interest rates, the swap charged by brokers was increased. I mean the difference between two interest rates in an instrument. For instance, if you hedge EUR/USD; one short and one long, the swap charged is high (at least higher than before).

Which broker has lesser difference between the short and long swap of an instrument? I mainly work with long-term trades, and this is very important for me, as I see after few months, I have significantly charged for swap.

For canadians, i find MF global fx to be quite competitive in terms of rollover rates (swap rate). I also use Questrade and their rate is terrible. They charge a premium on their rollover rates.

I totally agree

checkout Dukascopy's swap rates, the difference between the long and short (swap spread) is very low, I haven't seen lower swap spreads than Dukas, but would be interested to here if anyone knows of better swap spreads
