Woma prices have actually dropped significantly within the past year or 2. I'm actually surprised they have dropped as quickly as they have. While captive breeding is now pretty common, most hobbyists were tight lipped until recently, so most propogation was trial and error. Now it seems more folks are willing to share their experiences.
This combined with there awesome demeanors makes for a great addition to the collection, and a sought after species. I became enamored with them some years ago, and several years ago I spent $4K on a group. I was able to successfully breed them the first time I tried, however, I hatched 1 out of 14 eggs from the first clutch...the rest, I just watched die and get moldy.
Through more experience and learning, my hatch rates have improved, and in '08, I had my first clutch with a 100% hatch rate. Still, the relative difficulty in getting everything just right, when compared to other pythons, makes some keepers hesitant to attempt breeding in larger numbers from what I have heard from some other hobbyists. Of course, I still love 'em and will continue!
