Well, I could go on for hours about this; was I posted above was the most important highlights.
The fact is, right now we're in a sort of "boom" period for what I'll call grey-market beans. Medical cultivation is legal in many places and the number is increasing, and we have more people cultivating at home than ever before. Consequently demand for beans is at all all-time high, and the market has responded with dozens and dozens of new "breeders" most of whom are putting at mediocre product.
In the meantime Federal law still prohibits selling beans, or importing them, and there is a fundamental conflict here. While there are SOME legal (or quasi-legal) domestic sources for beans, at the moment the number is pretty limited. So the number of beans crossing illegally into the USA is at an all time high, leading to more confiscations. Also, I think its this increasing traffic in beans that's causing the Federal response we're seeing.
Still, I think the domestic bean supply is going to improve over time, albeit slowly, as more and more states permit medical use, home cultivation, or even outright legalization (like in CO, etc). As that happens, there will be an industry shakeup, with the "boom" followed by a "bust" cycle.
Once cannabis is TRULY legal, most of the "pollen chuck" breeders will probably disappear. Why pay $100/pack for illegally imported crosses of "elite" strains, when your pal can make equivalent quality beans in their basement and will send them to you for nothing or just swap for yours? As the legal situation improves, there will be more demand for consistency in quality, and I think it will result in a smaller number of breeders, but of higher quality.
To answer the absolute first question, the absolute "stealthiest" possible source of beans is you. . .make your own. If you have a little bit of knowledge, technical ability to make the beans, and can resist the urge to have the "latest greatest name", then you can easily make a several years supply of high quality beans at home by yourself. I think the hardest part of this is starting with parents worth propagating.
