Into Gundams? You should see my room :p
Anyway, I love building them ^__^ As for the Hobby Japan/Model Grafi comment: Not only the Japanese do crazy things... I know a few fellow modelers who do some really nice mods, and whatnot (Example: http://fichtenfoo.home.comcast.net/index.html Foo's custom decals and paint jobs always please ^__^ )
As for my kits, I only have like one up on my site, here's the link, anyway: www.blue-devil.net/chaosgear
I don't do much customizeing, maybe a few custom schemes, that's about it...
And Re: Patlabor Kits: The old 80s/early 90s kits, the rubber leg joints may eat through the plastic... If you notice on my site, I replaced them all with fabric covers... (They're really easy to make, just make like a pattern from the rubber piece, cut out the fabric and sew away! )
Also, if you want to learn more, you can always come over to ChildofMecha.com, I lurk around there, too, but they're really knowlageable and all ^__^ you might like it there
Any questions you have, just ask!
