The Mac-II songs/soundtracks are pretty good.
Wrt to the toys, I think only the VF-2SS was released by Bandai as a 1/100 HG(?) kit.
I have not seen a Metal-Siren toy.
Btw, the 19 was never in MacII.
fwiw, Mac-II is not as infuriating as 7. For starters, it doesn't have monsters-of-the-week stuff. Secondly, it ain't canon so anything goes.
And Ishtar's THE Macross-babe, canon or not.
All things considered, the only thing really infuriating about MacII is the english-version of Ishtar's Mou Ichido Love You song.
I'd warmed up to the dubs of MacII. Still weak, tho, but tolerable nowadays.
