Matt,
You know what I'm getting at. In one breath NWH is slagging of 'DIYers' and bragging he only buys off the shelf stuff - because he can - saying he wouldn't mess about in sheds with gaffer tape, and then in the next post he's trying to flog some second hand DIY kit for £70 and wants cash and won't give a receipt.
Personally, I wouldn't buy anything from him; he sounds dodgier than a NAAFI watch.
