Yes. Rob MacInnes at Glades Herp has a really impressive pair (or trio?) and he produces some each year.
Also Chris McQuade of Gulf Coast Reptiles does them. I'm sure there are some others too.
I do.
Paraguayans aren't quite large enough but my Bolivians produce. First clutch this year didn't get fertilized but hoping the second one does. My male is a lot smaller than my female so sometimes he has trouble : )
