Here is my 2 cents, I have a Orion From seemecnc.com its a delta, comes fully assembled base on the Rostock MAX kit just smaller. Steve and John are great people to work with and has a very helpful forum. It also comes with sdcard with a couple files on it, I actually set it on my desk scrolled through the sd card menu and clicked print and I could not ask for a better first print. and its open source.
