I'm working on my Iguana from Khurasan Miniatures (http://khurasanminiatures.tripod.com/15mmscifi-vehicles.html). It's a really cool vehicle and it actually fits great with my Warthog from Antenocitis Workshop.
The iguana's suspension allows for a lot of variation. I plan on getting at least one more and I'll have that one all the way on the ground, instead of this version with is as high as it goes. Each wheel pair can also rotate so if you wanted to have some really fancy wheel and suspension position you could.
Also, the casting quality was superb... I really like this model.
I've placed the finished Warthog (I just got another one to build) next to it to show a comparison.
I still have most of the highlighting to do, and the decals.
