I can recommend (and also have live account with no problems):

http://www.oanda.com
http://www.marketindex.de (Oanda Platform)
http://www.alpari.co.uk (MT4)

Avoid CMC.

BTW: I have no Issues with Oanda. There are seldom spikes there but there was always a rollback previously in case the spike was a wrong one.
