Here's a heads-up for GM fans with news of 1/144 GM II Cannon Conversion Kit as 'Appendix' with Hong Kong very owned 'Model Kit World' magazine. It's priced as HK $40 so the commercial pricing after shipping and agent fees should ranged around 10 USD. I had taken some pics of the magazine on the finished product of 1/144 RGM-80 GM II Cannon, in different colour scheme, by professional modelers. You need a HG GM II as an inner frame to complete the model.
I would say the magazine is rather thin with marginally acceptable printing quality and it's mainly paying for the 1/144 RGM-80 GM II Cannon plastic conversion kit. In my opinion, it's still reasonably priced for an alternative and as especially if you are desperately wanting to build your own 1/144 RGM-80 GM II Cannon, now that it's cloudy on the certainty about 'Big B' producing the official version. I didn't have it for myself cos I'm more into 1/100 scale but had bought it for my friends.
