<heavy sigh> My history with SD is just a little bit different. I purchased the SD2 with enclosure because it was assembled and it was shipping. In the lesser expensive 3D printers, these two items were real selling points at the time.
I have experience with three 3D printers and 4 3D printer companies now. Solidoodle is not much different and in several ways better than some other companies. We should hope for more, but in these price ranges, everybody is straining with supply, demand, customer service, inventory and who knows what other issues.
So I come back to my main buying concern, is the printer shipping? If not, find one that is. They all need calibration, they all need enhancements and before you know it they will all be obsolete. So, get one, mod it the way you want, settle on the kind of prints you can live with and print with it until it can't print no more.
