Of all lab software packages I have used now, MediaLab and DirectRT were not only the most flexible tools, but also the ones which were most easy to handle. The programming is so easy that even an inexperienced research assistant can create basic experiments within a day of practice. And the two programs are capable of combining nearly any kind of stimulus and response you may wish to use for your research. Most importantly, the service provided by empirisoft is exceptional. In fact, I can't think of any better lab software for psychological research.
