The following ads are from some of the magazines I have found. If you know of others, please let me know and I will add them to the list.

 Exoto's Hummers todate, are by far the best Die-case model that I have seen and well worth the cost over the others I have seen.
Exoto "ThunderTrac series, a unique line of collectors quality all-terrain vehicles designed in grand 1:18 scale. Each miniature replica is precision scaled from a wealth of metal and plastic parts with superb functional features." 

This model list for about $79.95, but it has a LOT of fine detailing! Very well built.  
They have 4 versions: a black Wagon, Desert Storm (Tan), Cammando (Camo), and the red 4 dr softtop.
