Just came across this at Robot Kingdom:

I don't remember seeing this set before. Looks like a cool upgrade kit for Metroplex. I have been buying the Unique Toys War Lord combiner and am satisfied with the quality for the price. $35 seems good for this upgrade kit. Might try Robot Kingdom out for the first time and pick this and the Planet X FoC Swoop up.
