I just entered the world of Gundam. My first venture was buying a 'Metal Material' Strike Gundam (
http://www.timbrisko.com/tbdx/strike.html) which led way to picking up a few 'SD' Gundams...Then finding out more about the TV/Movie/OVA stuff.
So, lets hear about how you got into Gundams, what toys/movies you've got and all that good stuff!
