I have tinkered with the gTec SARAHA system in the past, though it has been several years and the systems may be better now. We were recording in a fairly controlled environment where we had used wet electrode systems successfully without too much noise. The signals we recorded from the dry electrodes were pretty noisy and were extremely sensitive to movement artifacts. It is possible to record with dry electrodes, just know that you'll need some serious offline processing to clean the data, and you may want to have extra trials if you are trying to measure evoked potentials (try to improve your SNR).

scientists need to improve SNR with dry electrodes. In my opinion, these are not good at the current development level.

I have used dry electrodes before (not from ANT though) and they have worked just fine for me. Sometimes you might need to amplify the signal and apply several filters but they are still a great option. Depending in the research you want to carry, you might neeed to consider if using dry, gel based or wet electrodes.
