Personally I'd be ok with a longer shipping time as long as I knew what I ordered was good quality. I'm in the same boat trying to determine a good source and no matter which one I pick I need to go ahead and plan on some type of testing to make sure I've proven the quality myself and not relying on anybody else's opinion.
I don't mean that as a slight to anybody but let's be honest...can you really rely on the opinion of somebody you've probably never met when it comes to your health and safety? Don't get me wrong...there seems to be some great folks on here that are genuinely trying help mitigate harm to others but you ultimately have to protect yourself as best you can and trust your own research.
