Someone in Malaysia offered to swap a Soundwave for a Sideswipe (which I found at a BigW)... but now I can't find a second one for him.
If anyone sees one (must be the Diecast one, and must be RPMs NOT Speed Stars), please let me know. It should be about $5.

If by chance you find the RPMs Soundwave (not the Speed Stars one), please let me know.
