OK fine.
But I need to know a bit more detail so I get the right ones - so I thought I'd check with you lot.
A quick Froogle reveals a huge variety in the price of sets, in the number of feelers per set, in the range of gaps they can measure, in the steps between the gap measured by each feeler - and I dare say in the quality of the sets (longevity, accuracy?)...
I do realise this is an "under-a-tenner" issue


Any advice welcome
