My point of view
The Meister's accredited list is a very reliable source of casinos who will provide fairness and a decent service.
Never the less, I guarantee you that there are several other sites which will provide you with an outstanding experience.
I believe in one thing, there are over 2000 gambling sites out there, probably up to 3000. In my opinion, 90% are pure scumbags and morons who no crap about running a gambling site. The other 10% you can rely on.
That means that there are around 200-300 sites which are worthy to give a try, The acredited list on this site is quite good, however it doensn't mean they are the only ones.
I have played at Bet365, Titan Poker and Poker770 and all of them are excellent operations which are not here. Bet365 is amazing, Titan and Poker770 nothing great, but decent.
