Have fun!  And if you treat the kits like any other plastic model, you will get outstanding results.  Don't let the snap-fit construction fool you, Bandai has it all sorted out unlike everyone else.

As Klik already mentioned, Bandai is the Gundam model mfg.

The kits I have are injection molded styrene plastic with poly vinyl joint inserts for reposing after assembly. I've built only one of my kits and I didn't need to repose after completion. 

The fit is good and the 1/144 scale series is very affordable. 

It depends on what you're looking for. Bandai is the only manufacturer of Gundam Model kits. They range in detail ( and price) from low grade, simple kits to high grade or even perfect grade. 

Kits come in many scales, depending on the subject. Armor kits come in 1/35th, mobile suits range from 1/144 to 1/100, even 1/60 and 1/48 th!
