Combat Creatures Terrifying Tyrannosaurus is on Shapeways now for $16-$24, depending on which version you snag. It's a mirror-flipped redeco of Rampaging Rex, so it's not the exact same sculpt... except that it totally is. Manufacturing on demand offers some unique capabilities with a minimal amount of work, and "flipping" a figure is certainly a nice perk! Order yours here.
Also, Nick Tyranno on The Allspark forums got Rampaging Rex in Sandstone, and posted some shots - it's worth a look!
