If you're fortunate enough to get more than one option offer on a script you've written and are trying to figure out who to sign with, I recommend going with the producer with the best track record -- even to the point where doing so might mean foregoing a decent option payment (around $1,000) versus a negligible option payment.
In my experience, track record -- how many films they've made and how consistently they've done so recently -- has been a better indicator of whether or not they'll be able to get your film made.
Two different companies were able to get me thousands of dollars in options -- but neither were able to make the movie. They also had few to no movies made, though they did have good financing connections.
On the other hand, a $100 option led to the assignment that got me my first film, and I worked with another producer with no option at all that eventually would've gotten set up as a little indie if I hadn't optioned the script to someone else first. Both these people had consistent (though not spectacular) credits. I think the consistency counts for a lot. People who get things done, get things done.
