Online survey?

My boss wants me to make a website that collects simple information from employees about the research they are doing. I am considering using a free online survey service. Does this seem like a smart idea? And if so does anyone know any secure, trustworthy and attractive ones that they want to recommend?|||www.surveymonkey.com - is VERY good. Some people do not like the name, but the service is great. Some big businesses (e.g. shutterfly.com) use that service - very reliable. You should try it!!!
