I have a Halfords advanced pro socket set and a ratchet ring spanner set and I've been happy with them both. Halfords seem to get a lot of stick on the forums (not this one generally) which is unjustified in my opinion. Whilst they can be a bit pricey, they have some good stuff and with the advanced pro stuff at half price at the moment you can't go far wrong.
As for Clarke - my trolley jack and axle stands are Clarke and they've served me well over the last 5 years so happy with those also.
