While it is probably not relevant for the original question, I happened to buy a Delta printer kit (Anycubic Kossel Linear Plus) after following @aaI3D’s advice from this thread, and I could not be happier with the incredible value for money.
This is probably not a good recommandation for someone looking for a “just works out of the box” printer to support a business, it’s a kit and yes it comes with a cr***ppy firmware by default, but for a hobbyist usage and for someone who is willing to put a little effort into understanding how it must be configured/calibrated, it has proved to be an excellent cheap investment.
In case you are interested I documented my initial experience with it here, (kind of like I did when I got my Shapeoko 
)
