First of all, there is absolutely nothing that says you can't post about non Macross in here. I imagine, that because a Gundam figure isn't an anime, it's a toy, he figured it should go in the clearly marked Toy section.
Secondly, there is a large amount of territory covered in this topic. Keep in mind that the Gundam models are all snap together, molded in color, figures. That means no glue, and no paint. Now, some of the smaller kits (and older kits) will require some paint to look accurate, but keep in mind that model building is an art, and you are the artist. Most HGUC, any MG and every PG will require not one drop of paint to look amazing. Most High Grades in 1/100 and all the ones I've seen in 1/60 won't really need paint either. Now, if it's not a model, but an actual toy you are looking for, yes, the HCM Pro line is amazing. Tiny Gundam figures with great paint jobs, great posability, and amazing detail for their size. If you are looking for some hand candy, this is your fix. Speaking of FIX, if you are looking for something to put on your shelf and look bad ass, the Gundam FIX line is perfect. Designed by Hajime Katoki, every figure of that line is oriented toword looking cool. Many of them come with stands for dynamic poses, and most of them have options to actually swap them between different Mobile Suits. For example, my FIX Gundam Ver Ka has removable armors, and a second set of armors to allow me to rebuild it as a RGM-79 GM-C, with a new sculpt and paint job. You would need to keep in mind, however, that these are display figures, not playing figures. If all you want is something to play with, MSiA is built for that. The figures are built almost entirely out of PVC, and they are very very hard to break.
Anyhow, just look into it. Gundam is easily one of the most expansive merchanise lines around. It rivals Star Wars in sheer scope, variety, and numbers. If there's something you're looking for, it's in there.
