jVoteSystem is what I was looking for. An extension that not only creates quick and easy polls, but also offers several features which attract visitors to take part on the votings. For example visitors can comment each of the poll option or even add own options to a poll. The admin interface is easy to understand. You can create polls in no time. Btw, a plugin that allows poll to content articles is also included.
As for the support, when I reported a little problem on the developers site he answered just a few minutes later.
So all in all it's a great extension already.
But from what I read on the developers site he is busy to add even more functions.
