FWIW: Where I used to work we bought supposedly high quality crimped cables from newark.com. They may have even been Pomona, but may had issues over the years where the crimps would "let go". I went through a period of re-making a lot of the cables.
The process of making a BNC cable end is exacting. The strip lenghts have to be "right on" and you need a "thin wrench". Fortunately, I had access to resistance soldering equipment, so you don't get solder on the gold pin. The solder cup of the pin has to be flush with the insulator.
The other method is a "HEX crimp which i never used.
I've done a lot of work with Triax cables which have two shields and a center conductor. These cables also had powdered graphite to reduce the effects of flexing. a 1 meter cable was about $100 USD.
Now I have had to adapt N's (1000 W RF transmitter) to PL259's (Dummy load).
Sometimes ebay might have "wires" from an "estate liquidation", so you can get someone else's collection.
Be aware that there is stuff called "test probe wire" which is very flexible and thick insulated.
If you have room a comb-like device is available to arrange cables on a wall.
