Which of the approximately 200 pre-existing, owned, tested and reviewed models over on cnx-software.com are you referring to? I'd rather take my chances buying something that already exists at a fair price, not last-generation vaporware sold at an unfair premium, targeted at those who don't know any better.
As for reliability, there are definitely some designs out there with heating issues and flaky wifi (missing antenna is common), but overall manufacturing quality doesn't vary much at any price point. It's not like these sticks are cheap because there's child labour involved, they all come from a small set of factories that rely more on volume to stay in business than anything else.
