Couple guys in Finland have had small problems with Moneybookers. MB had somekind of security problems with their software and these guys lost their money, but in the end MB gave money back to these players. So looks good.
One worse thing is that their witdrawals doesn't work well, at least to Finland. They promise cheap transfer cost back to your bank account, but money never comes. So, the guys have to send money back to bookmaker and make a withdrawal that way.
