The TI ADS1299 PDK is by far the best option.
33
This is a manufacturer-designed development kit We have the needed power supply, too!
34
This is only $200, versus $500 for the OpenBCI Cython and $495 for the HackEEG Kit.
35
TI sells the ADS1299 chip alone for $30-35, but it is in a 64-QFIP package that is very difficult to build by hand. It is intended for machine assembly.
