ILGM is NOT a top source for good genetics, I would avoid them. Other folks have already listed some very good US based seed banks. Also check out the Seed Cellar, one of, if not the biggest US selection and they carry seed from many top breeders like Mephisto, Ethos, Mendo2020, Dutch Passion and many others.
Also look into ordering direct from breeders, you will get the best prices and many include freebie seed of test crosses. Breeders that are easy to order directly from are: Mephisto, Jean-O-Genetics and Brother Mendel. Maybe
@Dankerson can chime in with a few more direct from breeder Recs, he seems very up to speed on all the new hotness.
