My win rate is pretty good with Golden and Online Vegas, but I pretty much exclusively play roulette.  The only slots I have played is Go For The Gold.  I do okay on that.  Once won over $600 on a $2 spin.  But, I doubt I am ahead on that slot...even at best.  With one bad time in April of this year, payouts have been good.  BUT...to do wire transfers carries a hefty fee; comes out to about $60 per withdrawal.
