What is the cost of an EEG device (electrodes and other indispensable hardware, software if available for standard office computers, or a whole package with a dedicated computer and software) that is of suitable quality for neurolinguistic research? My own attempts to find information on this were futile. The Wikipedia article quotes low-cost devices from US$ 100 onwards, but I'm guessing the very cheap ones are of rather limited use for research. There is also an OPenEEG project, but I'm looking for an out-of-the-box solution. The commercial suppliers I found online do not quote any prices.

I just need a rough estimate to what amount of money is necessary to do any publishable academic research, and how much solution for average research needs would cost - such as 500 Euros/Dollars, 1,000, 10,000...?

We were looking for an EEG device few years ago. The commercial offers were between 20,000 EUR for a 32 passive electrode to 50,000 EUR for an 64/128 active electrode. This included everything except the computers - some offers were without off-line data processing software. I never considered the EEG systems that were not mentioned in the method section of my research domain. And beware of the local regulations and ethical considerations concerning home-made devices for recording human biological signal.
