In alphabetical order:
- American Salaryman - his "The State of the Gunpla Union" posts are always an awesome read. Did I also mention that he's a very skilled gunplar?
- GaijnGunpla - his Canary of Death has really inspired me, showing me how you can mod a gunpla and transform the known form into something even more kick-ass. Also, the guy is a wizard with decals and masking :o
- Gundam Guy - the best place for aggregated and filtered (for your pleasure) news about gunpla (well, not only gunpla). And the guy still finds time to dish out masterpieces like this or this. He's got something I'd call a good gunpla sense - his modifications always fit the gunpla, make it look more powerful/detailed, without overdoing things.
- ガンプラ命- Z's "Real" Gundam Model Review aka Gunpla Inochi - another veteran gunplar. Apart from the "usual" high quality builds and WIPs, worth noting are the two (for now, hopefully more will come ;)) great posts about gunpla and photography.
- It's a Gundaaaaam! - his how to page is full of useful info and posts like this, this or this make me revisit this site often ;)
- Plamo Addiction - many useful (as in: don't make the same mistake ;)) WIPs interspersed with gunpla news, random and/or kickass gunpla pics, awesome tutorials and bragging about his GF (lucky SOB, she likes gunpla too :o)
- seven6398 - he's done his share of gunplas - look at that list on his blog ;) Nice, clean finish - usually matching and highlighting the original colors of the model.
