HGGS 1/144 Gundam Astray Gold Frame Amatsu Mina

I've been wanting to aqcuire this, and I'm waiting for the limited-run 1/144 Gold Astray to come in, so I can replicate in 1/144 my old 1/100 set*. All I need now is to buy me another 1/144 Blitz, so I can complete the "option" set parts. And probably another Red Frame Astray HG Unit, to get parts from.

*Here are the Astray Links that show my 1/100 set:
