There are some really good cheap prosumer level EEG devices on the market now, for example the Avatar EEG (http://avatareeg.com/) and a few of the Emotiv devices.
I've been working on a side project (https://octopusmetrics.com) that allows you to connect these devices to your computer to record, visualize and analyze your EEG data in the browser. I think it's great that there are people out there thinking about how to do this more cheaply as it'll bring _real_ EEG devices into the price range where it'll be more available to hobbyists.
