How much for a lose stilt runner?

Recently been offered a good condition lose Stilt Runner, how much should I be expected to pay for one of these?

I payed £11 for one that wasn’t great condition and £30 for one in great conditon!I’ve seen them go for big money on ebay to! If you are getting one make sure all red pins for legs are there and the clip to hold figure as these break easily!hope you get a good one love my still runner
