Replacement for //www.webservicex.net/CurrencyConvertor.asmx?

Hello all,

We are using XI and the web service http://www.webservicex.net/CurrencyConvertor.asmx to retrieve our daily currency converstion rates. But there are times when this site seems to be down, like now and our currency update won't work. We were going to investigate paid services that do this same thing for us. If you use something other than http://www.webservicex.net/CurrencyConvertor.asmx to get your conversion rates what do you use? Thank so much ahead of time.

Ronnie
