I know if I had more time, I would bought online, but I need to pick
them up this evening/tomorrow morning from a conventional store.

Looking for a good set of offset spanners, and a decent Vice grip, or
set if they are good value.

Snap on would be ideal but out of my price band.
I've done well so far with Halfords professional and Teng, but just
wondering if there are "bargain" unknown brands out there, that are
little hidden gems.

I'm after something that will last, not just be a "one job and
break/lose them" set.

Any advice? before I blow money at B&Q/Halfords/Local Autofactors?

Cost matters, but I would rather buy good now, and once, than cheap
twice.
