@Horizon, these are expensive devices. I pasted in this info from the FAQ page:

How much will my Alpha-Stim cost, and will my health insurance pay for it?
A: The Alpha-Stim AID costs $795; and the Alpha-Stim M device is $1,195. Many plans that cover durable medical equipment will pay for Alpha-Stim technology—we recommend that you discuss Alpha-Stim with your insurance provider.
I would not be hopeful about insurance paying although it's always worth it to find out. I bought my AS years ago from a distributor who bought the devices in bulk and was able to give me a really good price. I don't know if that's still done. You could call and ask about it.
I don't know about the Fisher Wallace, but do a search on it in our forums. There was some discussion of it. With any device like this, you absolutely should not buy it unless you could get a refund for most of your money if it doesn't work for you or do some kind of trial.
If it were me, I'd try the Transparent NeuroProgrammer software first because it's very powerful and about $60 to buy it if the free trial works for you.
They have 7 different types of sleep sessions you can choose from. I'm not sure if the trial software has that many since I assume the trial is a subset of all the sessions, but I'm sure the trial includes at least several.
It's a matter of seeing which would work best for you, but the session for chattery minds, which entrains SMR (sensory motor reflex), helped me the most. I would listen to it with headphones on my Sony Discman--yes, I am that much of a dinosaur!--in the evening. I think it's a 30 or 40 minute session.
