Best source for Jack Herer and Strawberry Cough regular seeds?

Looking to grow out some Jack Herer and Strawberry Cough to smoke and make some crosses.

Can anyone recommend the best breeder / source which offers the best quality / high for these genetics?

I've never found a seed form of strawberry cough that I like, but I seem to recall someone here saying Kyle Kushman has come out with his own seed version, so I'd go with those if you can find them. I love the Jack Herer X Critical mass from Delicious seeds, has the Jack terpenes along with incredible production.
