Can anyone recommend a good screw/bolt extractor set for removing fixings with rounded off heads etc? All the ones I can find seem to be cheap Chinese rubbish, and I don't want to waste money on something that might not even last through the current job I need it for!!!
Something like this might suit. Quite expensive.

Screwfix are part of the same group as B&Q. They both do a similar set in "Erbauer" brand for one-third the price.
I have a set of Irwin brand extractors. They haven't had much use, but they worked.
