Hey dude, i'm thinking to buy in the near future some devices too. (still thinking how it will cost me because i'm not from USA).

I have this two in mind

There are some device that has an all-in-one solution? (EEG+GSR+Heart Pulse, etc bio+neuro?)

I'm really interesting in a good biofeedback device, because the last weeks i think i'm getting a nasty "snapback" i'm expericing anxiety, i detect it very easy because it signal a weird sensation in my stomach that can last 30min/1h. So is a priority to me to know how can i overcome that sensation without the need to do mindfulness meditation or moderate/intense aerobic exercise (two of the stuff that work for me to relax and probably tigger the relaxation response).

Cheers
