CZ Aficiando,
I don't remark on items I don't have or use. So to answer your question....yes I own a Ventcore for my CZ-75D. I seldom use it. I prefer the High Noon AIWB holster I bought after dealing with the collapsing nature of the Stealthgear holster.
The Stealthgear prices ARE way beyond ridiculous. They are nearly 3x higher than what I consider the Gold Standard of the industry, G-Code (tacticalholsters.com). The hybrid holsters are more labor intensive to manufacture. Thus, more costly and to what benefit other than offering a holster for one's weapon that another vendor may not offer. Furthermore, hybrid design holsters, where only half of the holster is kydex and the other half a synthetic, collapsing material, is a problem waiting to happen.
You fanboys of various companies and their products always amaze me. It is as though you have ownership in whatever company is being constructively criticized. If you cherish a hybrid holster design along with paying thru your proverbial nose for it, then so be it. But for my money, a 100% kydex holster far surpasses the inherit problems associated with hybrid holster designs.
