I don't know about south of the border, but up here in Canada, Jungle corns are doing very well. At several of the reptile shows we attended this summer folks were asking us for them. It's actually the reason why in 2007 we will attempt to breed our two albinos jungles for the first time. I also picked up another normal jungle female hatchling this summer.
Myself, I really like them and I'm hoping in future years to dabble by introducing some of the corn morph colours into the line. Don't know how successful I'll be but it's worth a try.
