I am hoping for a home birth, with a pool, but would like to have another form of 'natural' pain relief up my sleeve for before I get in the pool, TENS seems the obvious answer. I have looked on eBay just quickly and you can buy brand new ones ranging from £15 up to £60-ish, is this a case of paying for a name, or does it really mean better quality, since I am only intending to use it for the labour, I don't know if it is worth paying £60 odd for something that I don't even know will help.
