There are some halfway decent kits you can buy pre-made. It's what I do. Saves me a little hassle and I know it's all in 1 spot. I add another small bag for pills and other more consumable things like Band-Aids and tape. Amazon has some decent backcountry pre-made kits or I usually buy mine off MidwayUSA. It all depends on what you need it for. But for me, I find that if I shop around individually I'm more apt to cheap out and not include stuff just out of cost... Easier for me mentally to just buy the kit and call it done. But that's just me, and I have very rarely been called normal... so....Would you say, for a general first aid trained person. Is a purchased kit typically adequate, or do you have to hunt around to build your own? I'd love some reliable sources on where to pick up a good back country (lightweight) medkit. Beyond the bandaid, neosporin, gauze pad kit that the walmart sells.
