TB listens with interest... ...I was thinking of the £100 Clarke one, but is that too mickey mouse? I imagine the Snap-off one will put it beyond my price range...
I do not rate the clarke tools I'm afraid. I have now had to return my Clarke grinderette 3 times, torx bits keep breaking, the toolbox I think was a total waste of money..... the only good thing I had from there was my Mig Welder...
For about £100 get a Sealey off Fleaybay 
I agree that a lot of the Clarke tools aren't that great - my knuckles agree every time one of their sockets splits
. Bad news when you rate Halfords way above Clarke 
Never really rated Sealey either, due to a couple of rather naff torque wrenches I've had from them.
Tempted to pay more attention to what I see other people using, and go from there... ...my birthday isn't for another month 
Partiularly as its the same stuff 
I must say, I am yet to break any Clarke stuff (but I do buy the pro items)
Apart from silly odds and sods, I only ever buy Clarke Pro, as Clarke's standard stuff is like toffee.
I can't argue with Machine Mart's willingness to post out replacements (without needing to see broken one), but it doesn't cure the pain of knuckles on drive/car/brick

I have more faith in the Halfords ones, so tend to use them more. I have broken a Halfords one - it split on a particularly stubborn Citroen locking wheelnut

- but broken a fair few Clarke Pro ones now.
I still maintain, at trade and/or sale price (only a few pence difference), the Halfords 150pc is an ideal 'starter' set for Omega owners looking to do their own work. Yes, I think the older 150pc set is considerably better than the newer one with the red bit case, but still worthwhile. I understand and accept all its shortcomings, but my 2 sets are still my weapon of choice, as many members will confirm.
That said, my Clarke Pro ones have their niche's - DBW throttle bodies for one (torx socket too wide on Halfords - doable, but easy to round off), and the true Hex sockets for the stubborn ones.
I'm sure if I did as much spannering as you, Mr DTM, I too would buy better tools, be it Teng, Snap-Off etc. But for the hobbyist weekender, I'll stick with the 150pc set.
Mind you, the Halfords 'Professinal/Advance' screwdrivers are shite. I got them dirt cheap, and still think they were poor value. Mind you, I think the Clarke ones I have are shite as well. I tend to always use some overly abused Draper Expert VDE for sparkies, due to comfort/grip/power.
