It really depends if you, in the future, want to sychronize the GSR data with other data streams, then iMotions is definitely recommended. It is a modular system, so you just pay for the core and the sensor module you need, such as GSR, ET, etc etc....

If you have matlab at your univercity do it yourself (for free):

Thanks for the advice, Rytis. I'll probably look at alternatives since I've figured out that it is too expensive for a single project.

Have a look at lab streaming layer (LSL): https://github.com/sccn/labstreaminglayer

Thanks for the advice, Dennis! I'll have a look on it.
