We're in east Cheshire.There's a thread here that gives a few options:
I have some old power packs that havent been used in over 10 years which are perfectly serviceable and PAT tested. Does anyone know if there is a site where you can buy/sell scientific equipment? I was thinking along lines of getting equipment abroad to support science in developing countries...community.preproom.org
Also, let us know what area you're in, I'm sure if you're nearby anyone on here, you'll get some takers.
