For DMM leads, I'd recommend skipping the cheap crap and get decent stuff (with silicone leads as they're very flexible). The reason is chasing down a fault that's actually caused by garbage test leads is beyond aggravating IMHO. If you're only after a decent set of basic test leads, I'd suggest getting
Chinese market Fluke TL71 test leads (i.e. under 7USD to Denmark).
Sets offer a better value, and I'd suggest
Probemaster. Much better value than Fluke or Pomona's sets IME, and in the case of their spring loaded probes, are better made. They're a bit unusual in the sense that they sell directly, but they do ship internationally. FWIW, I prefer the 9000 series stuff to the 8000 series for PCB work as you don't have as much weight hanging off of your test point which is far more likely to pull the connector off of the test point. The
9104S Deluxe Electronic Set is an excellent value (straight retractable ends will work with pretty much anything). They also make really good quality oscilloscope connectors (Tee's and such), as well as filters.
For silicone banana to banana, or banana to crocodile, there are decent offerings on eBay and the like IME.
For an oscilloscope, you don't need to spend a lot generally speaking (don't get the cheapest adapters or connectors though; older ITT Pomona can be had as NOS at reasonable prices). In the case of probes, if a 100MHz probe would do, the P6100 models available on eBay, Banggood, or Aliexpress would do nicely, and come in ~6USD per shipped (
examples). There are others rated for different bandwidths, as well as high voltage. Even reasonably priced differential probes if you find yourself in need of any of these in the future.
In the case of RG58 BNC interconnect cables (50ohm),
Make life easier (eBay seller) makes up decent cables that are well priced. Useful for both a function gen and oscilloscope.
