>people ask me to try to repair something but i don't have the odd bit.
I'm assuming by repair you mean electronics and phones and such, not like a car or something.
In that case the cheapest option that'll do that just fine is those 117 in 1 packs in the bundle section, I think I paid like 7$ for mine at the time, and it's what I carry with me when I want to do field-repairs somewhere. It's got any bit you can want, plus guitar picks, suction cup etc, for phones specifically. The handle is cheap plastic, but for electronics you barely ever need real torque so that's fine.
Picrel are my bitsets, left to right:
>117 in 1 precision screwdriver set
(Handles are on the backside). Gotten from the bundle collection for 8€. This is enough for 95% of tasks and what I take with me if I don't know what to expect for some repair. If you have no bitset at all and want to get by cheap, get this.
>Ratcheting screwdriver with bits in the handle and rotatable by 90 degrees
5,30€ in the bundle section. Pretty heavy, not good for on the move stuff, but I've started using it for repairs in the house that need high torque a lot more, as you can flip it 90 degrees and gain leverage
>Ratcheting screwdriver small
Lighter, but other than that a worse version of the previous one
>Original wiha set
I think it was 15-20€ at the time, all metal construction, this thing was amazing. Isn't being sold for many years though, so now it's all fakes. I abuse the shit out of this (as you can see from the handle) and use for example my pocket knife tweezers to gain leverage etc. If they still sold this I'd say get that, but they don't.

I also got some super cheap green 32 in 1 screwdriver set, it sucked so much ass I gifted it to a relative's kid as a toy. Don't get those.
As the other anon said, ifixit is fine, but functionally no better than the 117 in 1 set; except the sets that have those microwavable heat pads to melt glue, those are pretty neat.
