I'm a bit late to the party but nonetheless decided that Kotobukiya's Metal Gear REX needed a proper review. Just released toward the end of December this 1/100 scale kit retails for $87. It's smaller than I thought it would be for that price tag, coming in at about 7-8 inches tall. It's also incredibly smaller than Three A's 1/48 scale release but a much better prospect for many considering Three A REXs retailed for $470 (most on eBay are now going for $700-800).
I feel as though this hasn't gotten enough attention since this posted almost half a month ago...
After about 20 days of work my Semovente is ready for weathering. For the most part things went well. The colour scheme looks okay and aside from a few areas where my paint coats were too thick the digital camo looks pretty good. Paint went well on everything else. I did lose a few pieces somehow, including a bit of handle bar that goes on the rear of the kit. I may try to recreate it if I can find some piping thin enough but I'll likely just pretend it never existed in the first place ;)
