Alpari: lots of slippage.
InstaForex: a hassle to get my money back.
LiteForex: stop/limit orders too restrictive, a hassle to get my money back
LMAX: great spreads, but insane slippage during big news.
FxPro: good broker, but no microlots
Haven't tested MB trading yet. Almost tested Oanda, but spreads during news are huge. Tempted by Liquid Markets as they pay interest on your funds. My biggest advice though is: stay away from Russian brokers!!!!
Over the years, I've put together a broker comparison chart, here it is: http://www.forex-central.net/broker-comparison.php
I'm pretty sure all of the info is 100% correct, but if you think I'm missing something let me know!
