No charge backs tells me the company cant full fill it's promise, or may be late and will be worried investors will pull out.
With BTC payment's they own your ass and can dick you around all they want, your not going anywhere.
With chargeback, you can dick around with their entire business model, and they have no recourse. No chargeback just tells me that they've already been screwed, and they're not willing to risk it again. They know they'll lose customers, but that loss is less costly than the potential for credit card fraud. That's how I read it, anyway.
Please ship USPS
You want to ship 6k in complex electronics using USPS? Now I am questioning your sanity. Chances are, it'll never arrive: returned to sender without notification, or be delivered to the wrong location. O.o
