The Hulk Mego was pretty sweet. I belive he was the best one, besides Superman, of course
http://www.megomuseum.com/marvel/hulk.shtmlPeople like Megos now because, they liked them as a kid and because they are not high tech slick perfect figures. In Japan, those old crude Vinyl figures, get remolded and sold for big bucks to collectors.
Just like those big dots on old comics and colors that go over the lines, from a design POV, there is something really cool about stuff like that.
There is beauty in imperfection, just ask Kidd Chip, he has made tons of money pointing this out
