You can't have everything.  Either you compromise on the model selection or you create your own.  As Rhia474 mentioned, the product must be market-viable and in high demand.   The time invested to develop such products must yield a high return in the marketplace, otherwise, the vendor wastes time and effort to make a profit.  The product you cite may still have a viable market because users are still invested in Genesis 3 Male.  But that is being overtaken by Genesis 8 & 9, and who knows if you will find this particular product in the bargain basement soon.

Meanwhile, hopefully, L'homme 2 will spark renewed interest and more content when it is released.
