The original halfords professional stuff made by snapon is no longer available and has been replaced now by the advanced range which I believe is made by someone else, the quality is still the same as far as I can tell though and they will still replace broken parts.

Snap-on stuff is MUCH more expensive, and the guarentee is far less useful to a home user as you cant just easily exhange things of a weekend, I cant see any point in having snap-on tools instead unless you are a business and have a regular visit from the snap-on man, for home use its utterly pointless.
