I did not ask the group *how* components are to be weighed - go botherif the contact pins are gold coated, you must consider the addiotional
weight of the precious metal. Gold is really very heavy.

I don't want clever Hans ruining my question with his snarky remarks, ergo a
explanation:
1. I found a way to import almost directly from China through a freight
forwarder (after a **lot** of hunting around and dealing with snarkiness).
The freight rate is roughly USD 12/kg door-to-my-door.
2. He only ships in 1-kg increments to me. Anything in excess is adjusted
upwards (air-freight).
3. I don't want to ask the shop in .cn to be kind and considerate because he
might sell me junk and how is he to know what I want.
4. I have a long list of parts that are available with prices so all i
need is a rough approximate of the part-weight and I can then ask the shop
to adjust a few grams this way or that.
But I have absolutely no idea how much stuff weighs..
If anyone wants to buy through me, at cost, let me know and we can exchange
info.. I'm open to the idea, but I don't know about shipping from me to you
(customs, lost pkgs, general patriotism, etc). Just don't give me grief
about this.
