Kettlebell (Hillsborough S6)

Hi, bit of a long shot, but does anyone have any of these that they no longer use please 8, 10 or 12 kg. I'm very over-weight and have not got the confidence to go to gym yet, however been looking online and they are so expensive I don't want to buy one incase I don't get on with it. Thank you in advance it would really be helping me out, physically, mentally and financially and much appreciated, cheers Donna
