Order cables already made up, order crimper's, order power supply
cables, order APP to OEM cables.

Spend the money, or solder it.

Enjoy

Or just buy a pre-fab power cable already if you can't handle making your
own:

I said that because I observed several guys on the reflector this
morning discussing buying the $50 tool. Apparently they never needed
it before, but felt that it is justified for the K3 assembly. Those
guys will probably never need it after the K3 assembly.

I will solder mine, but I remember reading years ago that crimp
connections are superior to solder - don't know why.

I am buying the kit, so I can't complain, but since it would cost
only pennies to do it at Elecraft it seems like it would be a
no-brainer if crimping is actually superior.

If you'd been reading this reflector since when building K2s was most talked about you'd know that some people bought $200 soldering stations and $100 DMMs just to build the kit. Every few months a thread would pop up about which solder station to buy. Some people just need an excuse to spend money. <g>

Personally I can't imagine how crimping an APP would be better than soldering it - quicker, yes, but better? I'm sure the difference won't be detectable by the guy you're in QSO with!

I have been told throughout my professional career that a crimped joint is more reliable than a soldered one but I am skeptical. Maybe a perfectly executed crimp is theoretically better but my own experience shows otherwise. Cars, industrial installations come to mind. I have witnessed plenty of bad crimps but frankly very few bad soldered connections.
