I have always found Halfords professional sockets to be fantastic value. A lifetime guarantee, a fraction of the cost of something like snap on but certainly not a fraction of the quality. Just stay away from silverline!
I will give em a call and see what they haveHi, He been mentioned on here before, he's packing up now to retire so stock is on clearance. He has a lot of the old names.

Whatever sockets you buy, always go for hex, and not bi-hex, hexagon sockets will not round the corners of stubborn bolts / nuts.
