I know this has been discussed a few times in the past as I've been searching through some of the posts on the old message board.
Someone posted a picture of a Snap-On/Blue Point tool which looks like a nice bit of kit. Unfortunately I can't find it on the Snap On site, there's no part number and no idea of price. Being Snap On it's not going to be cheap but you can never fault their quality.
Any ideas ?
Hanes have a similar digital one in their manual but I can't find that for sale on-line either.
