Wanted: would like to buy a Stokke Tripp Trapped high chair or similar

Does anyone have one of these chairs they want to sell? Happy to pay up to £50. Any colour and we don't need th baby fixtures. They go for around £50 on ebay but it would be mu h easier to sort out locally. We would also consider something similar. It needs to be a chair that our toddler can climb up and down from herself and that can be used by an adult if needed.

Thanks!
