I finished my BB Senshi Banshee by partially painting it with metallic markers. I like BB Senshi Unicorn-type mobile suits because they're SD-sized, can transform, and are cool and cute.

SD kits in general, not just BB Senshi, are fun to assemble, but unfortunately, they're not re-released very often, so the used prices are high and they're not easy to buy. Also, it's a bit tough that you have to buy multiple Unicorn-type mobile suits to display them in both forms. I hope there will be re-releases of SD Gunpla like BB Senshi soon...
