Most items from mandarake labeled as damaged box have great condition and box with tiny scratches.
About 2nd question: wait 1-2 years and maybe the'll do another run. Maybe there will be bundle with Armored parts, like VF-1J
There are Yamato/arcadia in 1/60 scale, like this: https://order.mandarake.co.jp/order/detailPage/item?itemCode=1107941522&ref=list&keyword=マクロス&lang=en
less detailed than KC or Bandai, but very good and stirdy
