Isn't the molex one a couple hundred buck a roos?
I dunno, I inherited mine when my dad moved out of state, he left behind his toolcase (and lots of other stuff) that had one in it, along with various other crimpers, mostly just there for the small-gauge strippers in them, I think, and the automotive-style crimper on one of them.

I have heard of andersons slipping out and doing all sorts of bad stuff, i don't know why they are so popular.
Because they can easily be setup to prevent this:
Although the one thing i won't have stock is a set of these for balancing, to avoid accidentally reversing the leads:
among other things.
Ease of connect/disconnect for frequent reconfiguration (or disassembly for charging, etc.) is likely another.
The main reasons andersons slip out is probably because there is no real strain relief on them, and either weight of cable or vibration ends up pulling htem out. It happens to me on various types of connectors that are low-insertion-force, that don't have a clip on teh housing to physically force engagement and lock them together, not just on ebike stuff but even stationary equipment.
Also, andersons have (at least) two versions of each contact size, one for low insertion/retention force and one for higher, and I suspect that all or almost all of the ones in Powerpole 15/30/45s used on ebikes are the former, but I can't tell for sure from the information avaiable. I don't think any of what I have is the high force version, except in my Multipole (SB50+) connectors, some of which are the low but most of which are the high force version, based on how hard they are to pull apart (regardless of which housing I have them in, or how much they've been cycled).
There are unfortunately no perfect connectors, as each has advantages for a particular use, and disadvantages for others.
