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

That's a good start. Build from there as need arises.

FYI, I'd recommend getting the 24" version of those leads. Unless your bench is HUGE, you'll rarely need 36" and it just becomes a mess. (I actually use a 12" set of those a lot, for measuring things with a handheld DMM.)

I 100% agree, I use 18 inch but 12 would be better.    36 would be a pain

A few reasons:
* Compliance is a huge one. Using the manufacturer's tool for their terminals helps prove compliance. First off, the dies make specific tool markings to indicate it's made a successful crimp. Further proof is provided by pull tests, but this isn't something that can be done in the field, so the tool marks are incredibly important.
* Cost of manufacture. Good tooling isn't cheap to make. As previously mentioned, the dies are made to high tolerances = takes longer to make. Proper QC (inspection and so on) isn't cheap either.
* Profit. It's a low volume product, and they want decent margins on it. So the final MSRP's tend to be rather high.
Finding the actual ODM really helps in minimizing costs, but good tooling is still on the pricey side for most hobbyist budgets (hint: Pressmaster, Wezag, Rennsteig/Knipex, Daniels Manufacturing, Sargent would cover most, if not all of the ODM's). There's used of course, and even if they're techically worn just outside of the No-Go spec, that doesn't mean they wouldn't pass a pull test (those that need such tooling can't take the risk as there's almost always liability issues associated with it).

FWIW, you can find decent used models of excellent crimp tooling on eBay here in the US/CAN. Just need to know what you need and be patient.

Edit: Looks like the colors start cycling a bit: https://en.wikipedia.org/wiki/Crimp_(electrical)#Wire_gauge_insulation_colors

In regard to 13AWG wire (or similar situation), you'd have to test fit the wire in the intended terminal/s. If the strands fit without being fouled in any way, then crimp it.  :-+

As per color recycling, that's quite true. But if you see the wire sizes, it's not hard to figure out (hint: the larger wire sizes will use non-insulated lugs, such as Panduit Compression Terminals).  :P On a side note, the smallest yellow (22 - 26) is sometimes represented by green (i.e. seen yellow terminals in the US on old telcom stuff, and a green nest for this size on one of my Pressmaster dies). One of those strange cases I guess, but also rare that you'd run into it.

Couple of references that might be of interest:
* NASA Workmanship Standards, Pictorial Reference
* NASA Workmanship Standards ProgramThese ^ will cover a lot of stuff, such as crimping to soldering and everything else in between. I'd recommend bookmarking these, the first link in particular.  ;)

Great resource -- thanks!

You're welcome.  :)

In regard to soldering, the Pace series are well worth viewing (they're old, but the information is still relevant).
