Theres a rumor that the slot machine in The Dust gives a higher Jackpot rate. Would you be willing to try that one out?
I should try this one. I've only done a few spins on it ever, and got a couple items, but nothing major.

Fought a one armed bandit with a slot machine on his back. Got Marcus every single time. However the payout was completely random, and after five spins it stopped giving anything at all.
First spin I did on one of those, I got a massive Eridium jackpot that just exploded 1 and 4x bars everywhere. Had to get at least 20+ Eridium from that. After that I think I just got some minor cash payouts and then, as you said, it stopped giving anything.
Anyway...I agree..Slots are golden. I've gotten tons of iridium from them, a lot of crap guns that were still worth more than I put in, and a few Blue (Or is it purple? I honestly can't tell. >_<) weapons, handful of duplicate skins, and various other stuff. Best thing out of the bunch was an Assault rifle that fired rockets. Did probably 40% more damage, and had faster fire rates/larger mags than most other guns at the time. Extremely brutal since I got it when practically every other enemy was carrying a shield at the time.
