There are also some possible functional equivalents available in bulk
and cheap, from Aliexpress. They are in-line power connectors used by
RC enthusiasts. For soldering to power wires, and come in M/F pairs.
There are multiple sizes, but so far I've only bought the two sizes
that fit standard 4mm banana jacks, and 2mm sockets.
10Pairs/Set 2mm Bullet Banana Plug Wire Connector Tool for RC Battery
US $1.29 Shop5585045 Store
IMC Hot 4mm Inside Dia Male Female Banana Plug Bullet Replacement 10 Pairs
US $4.02 Imc Digital Technology Company Ltd
(They are having their "11st Anniversary" :)
But basically search for whoever has the best deal and shipping.
Obviously the 'gold plating' won't have much if any actual gold, but
it seems quite functional.
There are also multiple sources of very nice high flexibility, fine
stranded wire with silicone insulation. In a wide range of sizes.
Not to mention ultra-cheap heatshrink tubing.
It's nice to finally have multimeter probes that measure 0.0 ohms when shorted.
Unlike the usual cheap, thin core commercial leads.
