Here's a good site with pics of all the different Iron Man armors, as well as most of the Legends related stuff released to date. There is a drop down menu under the Marvel Legends section that leads to the various related lines such as Spider-Man Classics, Hulk Classics, Movie lines etc.

I personally like the Series 1 Gold Variant and the Heroic Age Armor from the IM3 line. My favorite armor is the War Machine figure from the Iron Man 2 Movie Series.
