polldaddy lets you create polls and surveys.  The interface takes a little getting used to, but I think it’s a better tool than Survey Monkey and Zoomerang.  You can create a free account and even choose a free level of service.  The major difference between the free service and paid service are the number of answers you can capture.  I’ve only come across 1 drawback; the survey/poll builder interface does not work in Safari.  Check out this poll I made in 2 minutes.
