I have always been a big fan of grunt unit like the GM and definitely won't want to miss the opportunity meeting a fellow GM collector, especially one who is even more hardcore and dedicated than me in building GM kits. Certainly an eye-opening experience, visiting Don's house with feeling the overwhelming saturation of GMness, the moment I stepped into his bedroom.
Don has almost anything GM related stuff from vintage kits, exclusives, trading figures, bash kits, action figures to gasaphons. Even though Don hasn't spent as much time nowadays on model kits, his impressive airbrush skill could be seen from his works, take for example those built vintage GM kits from F91 series. My Gunpla skills are not even close to that level.
In the past, Don used to customize his GMs injecting unique characteristic and some ahead of time. A wide collection of GM kits and toys that had appeared in varies Gundam timelines from the first GM in O.Y.W to Shadoll Custom in Gundam Age. There were also great finds like the different Japan exclusive HG kits and the ultra rare 'A Baua Qu' Gundam Ride exclusive GM set.
