Thanks, I googled alot on it too. The ones just for depression/anxiety etc/ are around 500.00 but my doc rents them for 75.00 for 2 weeks so you can see if it works for you before you buy one. You have to have a script in the US to get one. Most places will let you rent to own. Some insurances will cover it, I don't know about mine yet, or if I can pay for it out of my medical spending account. I do know that I feel more relaxed at the end of the treatment, real depression relief takes 2-3 weeks. I will let you know...it would be great to eliminate one drug, especially one that causes manic side effects.I have only used it 2 days.
