If the things you mentioned would upset you if they happened to you, you should wait and order later.
If you wait until any bugs have been worked out your chances of having issues are lower.
If you want to be one of the people that gets to contribute to trying to find little defects that need to be improved on then order now.
Just my opinion. Others will likely say something different.
And everyone should remember this is Granite Devices first DD wheel offering.
It is going to take a bit to work things out. It seems there was not enough Beta testing on the end product, but things will get worked out.
We resellers and DIY guys have much more experience dealing with the actual DD wheels as we have been doing it for several years now. We can help them turn it into an awesome product.
Granite has been supplying us with the Awesome components for I guess 5 years now.
