At one time Ellis Island had very good mailers strictly based on coin-in. Many players were 86'd, but if any of you can still play there and were thinking of playing the good machines with games like NSUD in 5c through $5, don't bother. They now use theo according to the slot club.
I've been playing a few $1000 for several months on the NSUD and never got anything better than "play $10, get $10" and no food. And that may have been based on playing the 98.91% Deuces one day a few months ago.
