I think a few may have been imported in 2013, but there was a more significant import in 2014 of around 100 animals by Snakes at Sunset and managed by Marcus from SNDF. This import seems to be yielding offspring so I'd look for F1s being offered this year. Exciting times
Good luck with the DE. Let us know how it goes.
