Is RiddleMeThis the best solution for you? Lately, there have been a lot of new tools for conducting online questionnaires (the best known of which is free), so why use RiddleMeThis?
First and perhaps foremost, RiddleMeThis is going to be around a long time: we use it ourselves. Indeed, many, if not most, of our bug fixes and new features have been in response to people we work with directly.
On the other hand, we're not going to add "cute" features simply to add checklist items on a marketing factsheet, e.g. we don't offer "20 types of question" because this product has been designed by scientists for scientists and questions that don't correspond to useful measures have no place in our software.
Bottom line: RiddleMeThis is the only solidly cross-platform solution that works on the desktop, and it's easier to use than any of the other products (although not to deploy online -- but we're working on that). Aside from Survey Monkey, it's probably the cheapest option too.

Note: * having discussed this issue with several interested parties, it's clear that better accuracy is very important to many potential users, but being able to run cross-platform is a key differentiator for RiddleMeThis. I have a plan to offer millisecond-accurate timings both on the desktop and in browsers on both Mac and Windows computers, and possibly on iOS and Android devices as well. This will be after the initial release of RiddleMeThis 3.0.
