I'll 2'nd oz cactus garden as a great guy with lots of excellent strains also there's a few guys in Qld on Ebay that are sending out some good stuff , I just got a 10cc PE6 from colisp that's colonizing nicely There is also a user by the name of josau-w2akz9arb from the same town might be the same guy but he has slightly different options with very good reviews.
Strongly suggest reading up on some agar and LC TEK's then when you do get some in the mail you can expand it and not worry about how much you use!
