Seed banks and strain selection NEED HELP

I am hoping to order some seeds offline...i want some killer smoke but i dont like just going off the sites description...also i have been trying to find a seed bank where im at lease somewhat confident i wont be ripped off...seems like a even mix for every 5 people who say one seedbank is good another 5 say there bogus...so i would appreciate advice from people who have actually ordered seeds and know how to grow...also i have heard that out of the two seedbanks ive been looking at the most, (high-grade seeds.com and nirvana) that high grade seeds is bogus and that nirvana no longer ships to the U.S. which is important...so i need a trustworthy seed bank with good genetics and US delivery...any help is appreciated

i've ordered from high-grade twice, both cash orders
i've grown out their nl#5 and is a good indica
i think i've seen there is a bogus web site that masquerades as high-grade, so care is needed
i'm current growing a nirvana PPP, which seems to be a pretty nice strain
got the nirvana seeds from seed boutique, a UK based banks, again did 2 cash orders through them with no problems
