I've tinned 24 awg stranded and, because of how thin it is / how few strands there are, I found that it snaps easily. Hence, why I now prefer solid for thin wire needs.
Regarding Fleabay - every seller is obviously different, but I bought wire twice from 2 different sellers and in both cases it was old or poorly stored, brittle and crumbly. Caveat emptor.
