magnetic {ie cast iron/steel} pans (Builth Wells LD2)

Saving up for an induction hob: to work, it needs steel or cast iron based pans / frying pan - base has to be MAGNETIC. My old Le Creuset stock pot is; one tiny milk pan is - but everything else is aluminium. Does anyone have any unwanted pans, frying pan? Ideally, not too far from Builth (but am in Presteigne on a Tuesday evening, and Clun / Bishops Castle area on a Monday evening). Fingers crossed!
