You can build your own for much less money (and we did; our labs were full of jury-rigged gear made from gaffer tape and fencing wire), but using homebrewed prototypes adds a major source of variability to your experiments and impairs replicability. Establishing the reliability and validity of a new behavioural testing setup is a thesis in itself.

The local hackerspace crew built a thing like this. You may like it.
