TAMASHII NATIONS - New Mobile Report Gundam Wing - Wing Gundam Zero, Bandai Spirits Metal Robot Spirits Collectible

It really friends on your budget. If you've got l i t t l e m o n e y then I'd recommend something like the Gundam Universe Epyon. There's also an RX-78-2 in the Gundam Universe lineup. If you've got quite a bit more scratch you can look at something from the Metal Build series like the Wing Zero TV Version. There's also the Metal Robot Spirits line of figures. If you can coax his favorite mobile suit out of him then you can probably find a figure of it.
