I ordered from Ali Express and got 65/0.25 (known as 65/30 in the US) under the guise of 680/0.08. Paid about $2.10 USD per meter. Resistance measured horribly, but the wire was at least the right diameter.
Is there a good (perhaps Chinese seller) that people have ordered fine stranded tinned copper wire from and gotten what they ordered? Ebay and ali-express are OK, as long as you've dealt with the company before and they've actually sent you the cable you ordered.
Thanks in advance for any advice.
