Friend of mine bought from Build Volume.
He basically just said to avoid them.
The reason was to do with the adding fees on top of an order after the fact (ie. "hold stock hostage" after paid).
True or not, I've avoided them due to that.
I can highly recommend DIYelectronincs!
Quotes and ordering was prompt and professional.
I got very quick reply's to every email and shipping was a breeze.
We received our CR-10 Smart pro within 2 days after finalizing the order.
