Oanda is on wknd spreads now (At Oanda you can actually trae in the wknd on this wide spread, unique but not usefull for everybody), dig a little deeper and you can find what their spreads generally are. They don't have fixed spreads, but what they show IS what you can trade which is not always the case with other brokers. My experience is that Oanda shows spreads on a lot of pairs that are even better than on the interbank platforms with current liquidity.
