I remember awhile ago I tried Cirrus with a coupon. Their low limit for Let it Ride was either $5 or they didn't have it, so they weren't appealing to me and I never went back. Then when I got the free coupon last week (thanks!) I went to play, and Let it Ride is now $1 minimum! Plus, you can deposit as little as $5 there which rocks!
Another fantastic feature they have is showing how much play-through you have left. I did my first deposit for a 200% bonus. I put in $15 so I had to play $600 before cashing out. It was super helpful to actually be able to see how much more I had to play before I could cash out!
Anyway, if I am able to cash out without incident, Cirrus is my new favorite. Now I can go and spend $5 without having to spend 4x to 5x as much (like other casinos who have a minimum of $20-$25).
