Plenty of places on line such as Amazon, e-Bay and several individual on line sales.

Try searching for 'TENS Machine' and lots of products will show up. My wife used to have one to relief backpain, so I know there are a wide variety of products available, ranging from £20 to several hundred pounds. As for them being fit for your purpose, someone else will have to enlighten you. Replacements pads are available for a few pounds too.
