The snap on stuff is lovely, but is it worth the money over halfords professional that has lifetime warranty? I have the 200pc set and I've pulled RS4 engine. 'box etc. mostly with that set (a few impacts for the air gun added). Whilst I'd love to have the Snap-on stuff, I just can't see the value in it. I suppose it does keep money well...
The value in snap-on comes down to the easiness of it all. I can pick up a grands worth of tools of the van and pay £50 a week no interest. Plus if I break something, I'll likely have it replaced straight away. It is very expensive stuff, some stuff I won't buy in snap-on, but stuff like the impact guns you can't really go wrong with.
I have a Halfords kit too, it's what I started out with as an apprentice some 12 years ago and I still use it now, plus I have another set for home. The quality is still fantastic and I'd recommend it to anyone. It's rare I break any of the bits but if I do it can be a pain having to go across town to get them replaced. Not the end of the world though.
