My purchase list for my new lab -- budget $1000+, thoughts?

^^^^ this. Best soldering tutorials out there. After watching those, then you can watch the ones from John. Gammell and eevblog about SMD soldering, when the time comes.

Looks like a very good video indeed.

Aside from basic storage, final stage for me is buying some logic chips / opamps / ICs / etc since that topic is vast unto itself.

So far, mostly tooki's recommendations (not sure how much of each to get, I'm guessing 3 or so in case I damage any):

Also looking into the following:

ATTiny85 or Cortex-M microcontrollers (I already own an Arduino as well but it always felt sluggish to me)
LM317 (voltage regulator)
LM318 (voltage regulator)
LM350 (voltage regulator)
LM339 (voltage comparator)
LM431 (shunt regulator)
74HC595 (shift register)

I've sort of put the whole IC thing off to the end because it's a bit daunting. I'm aware there are some "outdated" variants out there but I figure they're still worth having for learning purposes.

Apparently there are miniature loudspeakers (was looking at the kits for Make Electronics), crystals, potentiometers, thermistors as well. Will have to tack on missing parts from the Make Electronics shopping list, so to speak.

rstofer:
Using Priority Mail for shipping from DigiKey, I get my toys in 3 days.  Even with my short attention span, this is fast enough that there is no reason to stock a bunch of components.  I have a large stock I will never use and, inevitably, what I have isn't what I need.

With Amazon, it's even quicker!  Sometimes I can get things the same day.

I would defer buying a lot of this stuff until I had a firm need.

I did buy the resistor and capacitor kits from Jameco.com but mostly just to get the cabinets.  These days I don't use through-hole components so the kit parts are used strictly for breadboarding.

https://www.jameco.com/z/00081832-540-Piece-1-4-Watt-5-Carbon-Film-Resistor-Component-Kit_81832.html
https://www.jameco.com/z/81859-520-PIECE-CERAMIC-DISC-CAPACITOR-COMPONENT-KIT_81859.html
https://www.jameco.com/z/81867-240-Piece-Radial-Capacitor-Component-Kit_81867.html

There are other capacitor kits but I haven't needed them.  I have had the kits for a very long time and I like having the cabinets with the pre-printed labels.  To me, the cost is unimportant.  I like having an organized assortment.

saturation:
If you're new to electronics, what to get can be daunting, but it is a catch 22, you don't know what to buy until you learn what what you bought does, which may or may not be what you want, once you do know about it.  For newbies, its more cost effective to a get a learning lab covering the basics of analog and digital electronics to make you an informed consumer.  With all ala cart gear and parts, you need a focused curricula on those parts to learn what they do, and it won't be as hand holding as the docs with these kits, which is optimized for its parts count for e.g.:

https://www.elenco.com/wp-content/uploads/2017/10/SC-750_REV-E-3.pdf

A kit offer this all in one, and Snap Circuits include adapters so you can use your laptop as a low end DMM, DSO, and FFT, so its all inclusive, nothing more to buy.  You'll expense $150 to get you going to know what to really do with your $850 at a later date or and sell the kit off on eBay, recoupe some of your expense.  As you move up, there are more "learning labs", such as pro kits, aka evaluation boards, like those for microcontrollers etc., so the idea of using all-in-one boards isn't just for kids:

Enjoy.

FWIW, I find it better to order what you need and wait a few days rather than trying to keep a large component stock.

For the stuff you'd find rather common however, you could look into Tayda Electronics (i.e. Chinese made equivalents of jellybean parts such as 555 timers and such). They're based out of Thailand, so shipments tend to be rather slow; as in more than a month. But you can't beat their prices for small quantities IME either.

Just don't get crazy, as major distributors can get parts to you in a few days (Newark, Digikey, Mouser, Arrow, Allied, ... in no particular order).;

Besides, when ordering boards from Chinese sources, it tends to work out (i.e. order both the BOM from say US sources and boards via ePacket on the same day). So the wait time is minimal as both sources can have stuff to your door in under a week or so.  :-+

Keeps you from having to stockpile shit you won't ever need again (wasting precious lab/storage space). Not to say you shouldn't keep *some* stuff on hand, but don't get carried away. Plenty of threads as to what's best to keep on hand or not on this if you search. ;)
