I am planning to build an EEG amplifier using an instrumentation amplifier and 
an isolation stage for each channel.  I have been looking at Analog Devices 
chips such as the AD624 (low-noise instrument amp) and AD289 (isolation amp).
My questions are: Has anyone built an EEG amplifier with similar chips? Are there
other chips that might be better/cheaper? Are there any good references on the 

Any help would be greatly appreciated.
