I'm interested in buying one of these mostly for therapeutic purposes, and I understand from a five year old conversation with a retired escort that always kept one on the bedside locker, that the ones sold by Hitachi are head and shoulders above the rest. But where to buy one, I've looked in a few sex shops recently and all I've found are cheap and expensive imitations.
Can anyone help with info on where to buy? or are any of the imitations up to the job?
