This site has a forum which is VERY active, and has a lot of different breeders in residence.
You can also checkout Andrew Seike's page. Which is: http://seikereptiles.com/
Pay special attention to his Sunset skinks!
P.S.
If you live in the states, shinglebacks can run you several grand! I too wanted one once upon a time...
Good luck!
