Snap On Tool Mate.
I've been in the motor trade for nearly 10 years now & have used all sorts.
I make my living using these, and yes they are fu*king pricey but quality is 2nd to none. Lifetime guarantee too, which is handy.
Halfords Professional are also good depending on your budget, the same with Teng. I've no complaints with Mac Tools other than they tend not to have the aesthetics of Snap On tools (put a Mac ratchet/screwdriver/airgun next to a Snap On tool, you'll see what I mean), and when you're paying the prices of these things that kind of thing matters to me. Mac always seem to look like they've been made in a sweatshop somewhere...
If you can, try not to set a poor budget on tool prices. The kit that is ridiculously cheap is also 99.9% likely to snap/bend/shatter etc, or slip resulting in a nice injury. I have the scars to prove it

So yeah, in a nutshell spend a decent amount on tools, look after them and they'll last you for years.
