It depends on what you want to gain. Do you want to detect epileptic
discharges in real-time or do you want to record it and process later?

If all you want is to record raw data - you can try some
biofeedback/neurofeedback equipment. It usually means 2/3/4 canals and a
small, handy amplifier. The choice of electrodes is another matter - you
can choose between clinical and commercial models. I know only clinical
types. Usually, during sleep studies, we use disc electrodes and we stick
them with glue (Collodion) to a patient's head. This type does not require
using a special cap. However, if you consider getting a cap you won't need
glue (how convenient! ;) but you will need gel. This method provides good
quality signal but is a bit uncomfortable for the user because of the wet
gel and you can't be sure if gel won't dry out through the night. If you
don't need a high-quality signal you can get dry electrodes - they are
sensitive to artifacts (as they move more on the scalp surface), but are
faster and more convenient to wear. There are also dry non-contact
electrodes but I have never used them. I suspect that it is the technology
behind all those "commercial" EEG headsets, but I don't know.

As for signal processing, you can use some open-source tools like winEEG or
EEGlab for Octave, depending on how you want to process data.
