I've been lucky and have cashed out on several NDBs in the past...Grand Eagle: $500
(actually was $470...$30 for check by courier)...from playing their 'WED50FF' $50 NDB. There was no initial deposit required...I received the check in 11 business days from the time of w/d request.Club World: $240
from a NDB of $100 (or maybe it was $200, cant remember), it was last Christmas' bonus gift. Money was in my QT account in less than 24hrs after w/d request Casino33: $50
from their $25 NDB for signing up. This w/d took a few days, kinda got the run around from these guys. But in the end, got paid via QT.All Star Slots: $50
from a $10 NDB for signing up. This required an initial deposit of $25 and a 1x playthrough of the deposit. Money was in my QT in 24 hours after w/d request and sending in fax back forms.Shark Casino: $200
from their $200 NDB for signing up. This was years ago when they re-opened with 'new management.' They have since been marked as a rogue casino. This w/d took about a month and lots of haggling. But in the end, they did in fact wire the $200 into my bank account.
I've also had a couple of NDB cashouts from Microgaming casinos, but cant remember the exact details right now as it was a long time ago. I think it was All Jackpots, ~$225
from a $25 NDB they sent via snail mail...and GrandMondial, ~$200
from freespins on Johnny Spector.
Good Luck evryone! Hope you win a fortune.
