Depending on your definition of "real". For those of you who watched the original broadcast series, StarBlazers was probably the first anime you saw. You watched as they fired the Wave Motion Gun for the first time and saw it obliterate a floating island. You held your breath as the relentless assault of the Gamalons threatened to destroy them. Your eyes, like mine, were probably as big as saucers as they found out they had to go into the Gamalon homeworld and take them out before they could acquire the device from Trelana.*
Now, for a mere $277, you can own The Argo. Well, a 1:625 scale model at least. One thing it has going for it is that it's metal, not plastic. Judging by the picture, it seems to be very true to the series.
I still have a soft spot for the final confrontation of The Argo inside planet Gamalon. When I decide to watch the show, I do so at night, lights off, volume up. The effect of The Argo's main guns firing every which way, the exploding bombs and rockets trying to find their mark, the sound of everything, is something that I thoroughly enjoy.
