If you like Microgaming, your best bet is to deal with the E-Processing family of casinos:
Royal Plaza
Vegas Joker
Old Samurai
Grand Casino Venice
Challenge
MusicHall
King Neptune's
Vegas Country
Floridita Club
Grand Hotel
Vegas Slot
I deal with every single one of these casinos on a constant ongoing basis, and the payouts are VERY fast. If I cashout Sunday night (and fill out the Winngings Refund Request Page on thier websites), I usually get payments in my Paypal or Prepaid ATM account by Wednesday morning. Now that's fast. Also, thier telephone helpdesk (via thier toll free #'s or freefone is the best around, and they are quick to resolve any problems, especially if you ask for a supervisor). They are professional and courteous.
The bad thing about E-Pocessing casinos is that thier email support is lousy. In many instances, during even a weekday, it take 8-12 HOURS to get a response to my query, and sometimes up to 72 hours (or never) to get a bonus credited. I got fed up with thier email support, so I use the phone instead, and thus far, no problems.
Unlike Proc-Cyber, this group doesn't make you jump through hoops to get paid, even on larger amounts.
However, they don't like bonus hunters and if they notice someone who is extracting winnings from some of thier sites on a regular basis, they will lock this player out. I got emails from them telling me to basically take my business elsewhere. I wrote to the supervisor asking if he could unlock my account if I played a certain amount of non-bonus play. After forcing this issue, he disclosed to me the criteria that the system looks for to spot "bonus hunters". (Not all MGS just E-Processing "Hotel California" casinos)
Now I am playing for cover at these sites with exactly the amount of non-bonus player required to stay under the raidar. So far so good.
But make no mistake. They know who I am. And at any moment, if they choose to lock me out,there would be nothing I could do. I think they are being nice to me since they are doing very well financially at the moment, and since I have been willing to compromise.
