Impressity - www.impressity.com

Impressity lets you create surveys for free. Unlike other popular survey sites where "free" survey package limit how many survey questions you can create or how many survey responses you can get, Impressity's survey service is unlimited and completely free. You just need to sign up and use it, simple as that.

Another thing I like about their survey site is it allows you to "embed" the survey inside a website. I can copy the "embed code" of my survey and just paste it into my own website, and it shows up perfectly. I have tried other survey sites like KwikSurvey, the embedded effect is horrible in comparison.

Also the survey templates are quite sleek and look professional, which adds to the credibility of the survey. I definitely would recommend this site to people who want to create a professional survey with low(no!) budget.
