Hi ive got mostly snap on and mac ,facom in my boxes but i did buy some swivel head ratcheting spanners a set for 40 quid which are good quality .
If you starting to build a set i would start with a blue point socket set get them on ebay around 120 and fill the box up with some like pro range deep sockets such as halfords or clarke but be aware if u use this gear everyday it will weaken and mess up ......neil.......
