Well I was in Adsa today a place I visit as seldom as possible.Anyway I though to take a look in the electrical section and found a Uniross X-Press 150 for £8.95 so I bought it.
I will get the batteries you suggest though zingy and try them.The only way to find out is to experiment after all.
Thank you all for your suggestions and I will come back and tell you how it goes.Greenies to follow.
