How many of each do u need laying around ? The cost of no-name SMD resistors and caps, is not much, as side from shipping maybe.
On amazon or ebay, you can probably get kits of 10pcs*30 values, for like $5
I hate trying to measure SMD parts with DMM probes, especially if they have crusty old solder on them. And I didn't find tweezers much better, like on my LCR meter.
