    Testing equipment??

    Hello all, I've recently went self-employed and I'm on the hunt for cheapish test equipment (for domestic use)? I don't want to be spending a fortune, as I will only be using it occasionally. I would even consider buying second hand, but I thought I would ask for a bit of advice, thank you! Phil
