Yeah - I paid =A35 at Netto, then saw the exact same model in screwfix for =A320.
It's a nicely machined bit of stainless steel, and checked against my micrometer the accuracy is sterling.
So don't be sore, even at =A330 it's a nicely made/working tool.
I suspect they may be product dumping because the battery hatch has a habit of falling off (gaffa tape around mine) - and it will chew through batteries if you forget to turn it off every time you put it down.
