With Snap-off you have to be really choosey now, as some of their stuff is a bit crap. I note that more and more stuff is no longer covered by the lifetime warranty. Its only real advantage is they make it easy to buy, and on the drip as well.
I wouldn't buy the spanners again, as I don't like their shape.
Their ratchet screwdrivers are the only ones worth having; the master set is expensive, but is actually good value.
Ratchets are excellent, and are available in lots of styles/lengths to help access, but by the time you've bought ordinary, long, flex head and stubbies you're talking real money. And similar quality is available for a lot less.
1/4" drive sockets and extensions
are well worth the money; SO ones are thinner but strong, and better finished than most others - I rarely use anything else on 15mm or smaller nuts. The 3/8 drive(I do have imperial and metric) isn't as good an improvement, and I'd need to win the lottery to justify 1/2" stuff. Although the long 1/2 flex head ratchet, which I used so much it's the only one that's needed a rebuild - I must have done 100s of wheel changes with it, and a lot of suspension work - owes me nothing. I might change my mind if working on trucks for a living, although most of the heavy mechanics I worked with only had commonly used sizes.
Specialist tools need a lot of consideration between cost/value/necessity and how much you actually use them, I'd rather buy a range of cheaper things like pressure testers(coolant, fuel, oil etc), bearing pullers and so on than just one expensive but limited set.
If working on interiors, or anywhere else where access to screws is limited,
THIS will pay for itself in no time. You can buy cheaper(and more expensive bit drivers) but the Wera one is the best.
I would prefer hand tools not to be highly polished, but it seems I'm in a minority
Tool boxes/chests? Just no.
