When I first started growing again a few years ago I was unaware of American breeders and so I bought from Seedsman and MSNL. Both had great and rapid shipping/stealth but I had really bad germination rates with MSNL (would never order from again...obvious old seeds). Had like nearly 100% germination from Seedsman.
Since then I have ordered from James Bean and Greenpoint here in U.S. and am very happy with both of them (may never order overseas again). Much cheaper to order here in U.S. for me without the extra shipping and for stealth etc. from overseas.
Back in the day I used Nirvana and was very happy.
